Kernel panic - not syncing: Fatal exception in interrupt - Eee Pad Transformer Q&A, Help & Troubleshooting

I am one of the many who have been experiencing the random reboots. I have seen talk about it, but have not seen anyone really looking into why this is happening. Some people claim it happens only when docked, or when SD card is in etc. Yet others post that they still get the reboots without doing those things either.
I have been monitoring my reboot problem very closely. I have yet to determine the cause other than it only happens when the device is put into sleep mode manually or automatically, and I am looking for some help from some of the DEV's around here.
When our TF's do this reboot, it is a system crash. When this happens, a ROMDUMP file is placed on the internal "sd card".
These can be viewed with a simple txt editor, like windows notepad. I myself can not read the code and understand what info it is revealing to me. According to an Asus tech on the phone this file can tell you what went wrong and made the device reboot. However the buggers won't tell you crap over the phone and want me to send the device in with the ROMDUMP files.
When I try and read the files, I do see one thing in common, in 99% of them, right near the end of the file, or the very last line before the crash, this line is present,
Kernel panic - not syncing: Fatal exception in interrupt
<2>[ 162.985309] CPU1: stopping
If our reboot issue is kernal based, which would indicate it's a firmware issue;
I was thinking one of the talented DEV's around here could fix us up.
Hell maybe even just a reflash of the current firmware would fix the issue.
Anyway, if a DEV around here want to or willing to look into this, I have some ROM dumpfiles they can look at, just send me a PM.
For reference,
I have a B60K modle

Thanks.

I don't have any more dumps recently, deleted them so I can't pull up and see what mine said to give you, but wanted to just say I was having these multiple times a day every day and it started once I bought an AData 16GB SDCard for the dock. Then I ended up removing that card and bought a MicroSD 16GB card instead and it has quit doing the random reboots, so definitely seemed to be something with my SDCard in the dock.

Post your whole log here (as .txt or .zip) and I will look at it.
I've had these once or twice but have always deleted the file.
The Kernel Panic is the kernel's way of telling you that something unrecoverable has happened and the integrity of the whole OS is in question. Think of a kernel panic like a BSOD on Windows.
I've never seen that specific one before, but a quick Google search indicates it may be a problem with I/O operations - like bad RAM or a bad SD card.

Thanks for the response. I have included 4 RAMDUMP files. I find these 4 special because they all happened in quick succession. Four separate reboots all within 8 mins of each other without any interaction of the device myself. I never touched the device, I just sat there and staring at the device rebooting 4 times in 8 mins. On the final reboot the device never came back on. AT this point I picked up the device and had to hold the power button down for over 10 seconds for the device to come back on to an Asus splash screen. This was mins after I did a fresh factory reset via the OS options internally then a hard reset using the hardware buttons.

...It's a bug alright...
It doesn't seem to be caused by the same problem though, just that the watchdog program invokes a kernel panic and reboots. Weird. I'll backtrace it later and see what's up.
sassafras

went a whole day without a reboot. I did have an odd lock up/freeze at the lock screen where i couldnt unlock the device or get it to rotate the screen. It was locked up tight. Held hte power button down for 20 secs before it shut down. Rebooted, no new RAMdump created. No issues since.
sassafras_, Did you have any luck reading those ramdumps?

I did - sort of.
They're all related to the watchdog program assuming it's soft locked up. Which it may very well have been, but since you weren't using the device at the time, it's hard to know for sure.
The function's that were called immediately prior to the fault were different, which to me indicates that it's just buggy software. Honestly, without doing a backtrace I wouldn't know, but I can't without a system.map from around the time of the lockup. I'm going to assume it's just buggy code from 3.1 and wait and see if the 3.2 release lowers the rate of these. If not, then maybe I'll do some more digging.

Is there any progress on this issue? I bougth a brand new tf and during day random reboots maybe 50 times. And that romdumps are appeared on my internal storage. I dont have external sd by the way. Im stuck.

Hi.
Im having a same problem with my Transformer. Its a week old B60 and its reboots probably 50 times a day and give me log files.
Also im using Honeycomb 3.2
I really want to find out what is going on

i guess its a hardware issue or something.
i'm going to give back my TF today and take back a new one.
if i get same errors, i'll let you know.

I posted a workaround that helps immensely for rooted tablets somewhere around here. I can't find it tonight, but it's in one of the other 'random reboot' threads.
sassafras

sassafras_ -
Did you ever find anything with this issue? I am on my second TF and it is exhibiting the same random reboot while sleeping issue as the first. I know you have a post on another thread indicating how to tell the kernel to ignore "oops" conditions - have you received any feedback on how that is working? I assume this requires root access, I haven't yet rooted my device.
I have collected a few ramdump log files, but as of now only one out of 6 shows a kernel panic. I am new to Android, and I am trying to make sense of the dump logs. It appears that these dumps are maintained in a ring buffer, so the last entries are usually somewhere in the middle, is that correct? All of them also have some garbage at the end, but I assume that is just another effect of the ring buffer strategy.
Like I said, I am new to Android, but I am a long time embedded and real-time programmer, and pretty handy in Linux. It seems to me that the log files aren't providing enough information, but I'm not sure how to debug kernel/system crashes in Android. If anyone could point me in the right direction of where I should look next to get more information on these crashes, perhaps we could get to the bottom of this problem.
From what I can tell via the logs, when the TF is sleeping, it wakes up from time to time for various reasons, then suspends when it is done. It looks like it is during this wake/suspend cycle that something occasionally goes wrong and causes the tablet to reboot.
I am hoping that this is a software/firmware issue (or a hardware issue that can be worked-around with software), because I really like the TF platform and this issue makes keeping apps like IM or email running while it the device sleeps kinda iffy.
Any help from the awesome experts here at XDA would be greatly appreciated, and I look forward to learning more of the gory details and inner workings of Android.

I have had the same issues. Configuring the kernel to ignore oops only helped a bit. The tf would still freeze in standby eventually (once a day or so). My supplier (i.e. not Asus) replaced it and my new tf (a SBK v2 one, unfortunately) has not rebooted once in 2+ weeks. So my guess is that it was a hardware issue (memory, something not coming out of backup mode properly, ...?). Not sure if one could work-around it in software.
Now, this was probably not very helpful but I thought I'd share my experience here. And possibly my tf suffered from an entirely different defect, although the symptoms were the same (ramdump logs from random reboots in standby, independent from wifi on/off, sync on/off, and lots of other settings I tried).

flipflipflip -
Thanks for your reply! I was hoping that it wasn't a hardware issue, and since I got two in a row with the identical problem I was thinking that maybe a software fix could get around it. After reading about your experience, I went ahead and returned it and ordered another one from a different source. Hopefully the third time's a charm!
I'm keeping my fingers crossed that this one is not an SBK v2, but I'll be happy just to have one without sleep-apnea!
This did give me a chance to load up ADB and poke around a bit under the hood of the last one, so if nothing else it is a learning experience. Hopefully I will have something to contribute to the community once I get my hands on a working device.

I know it's been a while (had a big work-related headache), but just wanted to post and let people know that I finally received a TF101 (B50!!) that seems to be working just fine - so I guess it was just a combination of bad luck and a hardware issue after all.
The only issue I have now is that sometimes when it is sleeping, it loses its internet connection (it still seems to be connected to the AP) - but I think I can work around that.
Cheers!

Observations as to why market breaks / force close, and other anomolies

As I suspected early on the issues boil down to corruption within the User Data or Cache partitions, less often on the system partition due to an unexpected shutdown of the device. Shut on these devices need to follow the proper shutdown routine as any linux environment. Following this best practice will ensure that all data is written out to its corresponding file system by flushing all cache, unmounting the file system, etc..
Here are the culprits of why we see so frequent random Force Closes, Market Resetting, etc. ultimately resulting in an unclean shutdown, corrupting some data.
1. The button we use is also a forced off button. Typically if you hold it down too long you are powering off the device.
2. Some times when in sleep mode you see the Viewsonic logo upon starting - that means that the system shutdown (most likely crashed).
3. If your running Vegan your hitting the reboot.. I dont know for sure but I suspect this is NOT performing a clean shutdown... (I dont have a copy of the source)
Anyway... wanted to pass this on... as last night my data partition became corrupt after using the Reboot function on the Poweroff menu of Vega 5.1..
shouldnt need source code to debug a dirty shutdown..Cant you just run an adb logcat? maybe run the shutdown command in a terminal on the device and pipe the output into a text file for later viewing
My internal memory has to be repartitioned every few weeks - I'm certain that something is corrupting it over time. I had massive FC's just a week or so back where the SD partition re-do was the only fix.
I suspect that this happens in stock, as well - the problem of course is that there is no fix for a stock user, other than a return / exchange.

I have been on stock since I got the device just moving to the newer versions when they come as OTAs and have never ever had to mess with my partition, so I don't THINK the issue is in the stock software. In fact, the only problems I've ever encountered were when I used the enhancement pack, in which case my screen started to become unresponsive and the calibration.ini I was told to try did not work. Since then I went back to 3389 and the device has been perfect ever since.
I could be wrong though and just very, very lucky....here's to hoping. Another thing to consider is maybe the memory is going bonkers for some reason. I've had flash memory that lasted forever and I've had flash memory that has gone wacky over a period of 6 months....even a wipe by the utility designed to do it doesn't fix it properly. I don't know how CWM wipes or partitions the memory, I do know there's supposed to be a special way to do it.
If it's not faulty memory off the bat, then that leaves something in the 'extras' being put into these ROMs. Maybe some of the newer tegra drivers or some coding to make the ROMs faster - I'm just saying, can't leave any stone unturned.
Has anyone that has stayed loyal to stock encountered these issues? We have to ask that question I think. Then we ask how many of the people playing with ROMs are seeing the issues, this would include people that have used CWM to partition and mess with their mounts initially.
I can say I've never seen data disappear from my internal memory or my SD and I can also say I've never seen multiple FCs except after putting in the enh. pack (keep in mind I got my tab on Dec 20something, so I had 3053 and then 3389 soon after).
The first sign of anything being 'corrupted' on it's own at stock and I'll be sending mine back. As an owner of Android since Android's been around, I've never had my G1 or MT4G (or any smartphone before it) become corrupted due to not being shutdown or reboot properly and while this is a tablet I think the fundamentals should be the same. Pampering 'faulty' memory is a risk. You can wipe and re-do all you want, but if it's faulty it's going to stay that way.
Ive done that but I guess you can say unfortunately I have had only clean shutdowns since then... The last corruption I had I formatted my data and cache partitions before I ran logcat.... Of course thought of that afterward....
Generally if any has FCs, etc. etc. run a logcat and post it here... we will be able to confirm this...
We could change the way the partitions are created and add a sync which will further reduce chances BUT will take a performance hit...
I am very surprised though as the EXT3 filesystem is very resilient to dirty shutdowns (more than EXT4)...
I reviewed the out of the box framework source on the google GIT and technically if a reboot command is given a clean shutdown is performed via the framework... but the widget on the shutdown screen I suspect is not calling the method properly or is not being called at all... All speculation at this point... But for sure there is corruption occurring..
Since the last corruption I switch over to pershoots kernel... Even though his kernel seems to be a little slower he seems to have included the latest drivers which other items relate to data integrity (im reading into the release notes).
NEO: The first thing I did when I got my device install CW, Vegan... Updated Kernels also... Never had an issue until the first time (yes about a day ago) I used the reboot feature of Vegan. That corrupted my user data. I suspect if you have not been performing clean shutdown then you are just lucky. Linux, like any other OS, even with Journaling if you do not perform a clean shutdown you will surely encounter SOME corruption. Typically the corruption is re-mediated by the the file systems integrity controls. You dont even know it happened... 1 in 1000 the integrity controls can not overcome the significant loss of data and thus results in crashes, etc. Some times the corruption happens in areas where are lightly used thus why you would get a Market Reset... that data is easily replaceable on the fly. Core components that require subsystem to run are not replaceable and thus why I had to reformtat. What upsets me is that this failsafe is not working properly most likely as its far too frequent.... I too suspect it has something to do with CW.
But again.. between the wrongly placed power switch, the unprovoked reboots (ie viewsonic screen showing when trying to wake up the device) and the reboot button possibly not performing a proper shutdown will sure increase the chances in a wider distribution of users. So it may not be a CW issue and just some poor design.
When I have time today I will verify if the reboot function performs a clean shutdown... if anyone has the time please post the logcat... Im going to be running around today and will try to get to it..

AFAIK they're running yaffs ATM. Next move is to ext4...
Read some articles about this several weeks ago, apparently many apps do not properly flush file caches. One of the articles was a Google developer post about file corruption along with their API method which did a cache flush prior to a close, then a bit later was the Google indication that they were planning to move to ext4 FS to further help alleviate the problem.

That's my point. How many times since we've had our Android and smart phones have we had situations where they are turned off or rebooted without the proper procedures? Power drains till they die, they drop and reboot, we clog them up with stuff or some app drives them nuts and they reboot or shut off....Yet you rarely if ever hear about a phone's data being 'corrupted' with stock software. Sure it may happen with official OTAs etc, but never just off-the-bat like what's happening with the G-Tab. But it's not happening to everyone either so I'm just looking to see if there's a pattern.
Even since the G1 and newer phones, you don't really hear about or see file corruption issues on stock software with these phones. It's when users start going to ROMs that you hear of issues cropping up. That's not to say it doesn't happen at all at stock, I just think we're seeing it in a more concentrated fashion here because of all the formatting, re-partitioning, etc. At first you hear, 4GB is a great partition size, then you hear there are problems so move to 2048, then you hear 256MB swap, then no swap since Android doesn't use it. Then dataloop for speed, then no dataloop because of critical issues. Rules and instructions change almost on a daily basis. I think it's more than these poor flash drives can take I find sometimes it's good to keep it simple.
I owned a Vibrant for a while...decided it was a PoS when at stock I was seeing bad lag (because of Sam's terrible FS). People said...do the speedhack, it'll be fast!, but what was the caveat? Having to reboot the phone almost weekly, sometimes several times a week, and people were seeing what? Data corruption. That's not for me. Give me something that is lag free (doesn't have to be a bullet train, just don't skip on video or audio and make sure my live wallpaper and drawer animation is fluid and I'm happy!). Point being....keeping it simple may help to alleviate some of the issues. If people are seeing these problems with stock, then you're absolutely right and it would be a point of contention that the failsafe isn't working right.
Otherwise it seems the stock OS on these things are able to self correct in most situations and it may just be some of the many tweaked features in these ROMs doing something it shouldn't - or, I may just be very lucky indeed.
I'm still dying to get the OTA - I haven't seen one since 3899 yet.

[Q] Phone stopped working and won't start again

Hi, I have a g1 that has suddenly stopped working - when I start it I see the t-mobile screen and then it switches to the android screen and just stays like that and doesnt start.
It stalled while making a call and I was not able to restart it.
I have tried wiping everything from recovery console (http://forum.xda-developers.com/showthread.php?t=566669) and re-flashing my phone with my old firmware (http://forum.xda-developers.com/showthread.php?t=811620)
I don't know what's next here - can anyone please help?
some more background:
I had the phone for two years here in the US and have traveled out side of the country with it for several trips with no problems whatsoever, however, this phone I have given to my niece who doesnt live in the US.
The reason i'm saying this is that maybe the cause is a radio problem of some sort...
Let me know if you think of something coz I really don't know what do to next
Thanks,
e.
First of all, wrong section.. (Please post in Q&A)
If you had poked around and used the search feature, i'm pretty sure you can find what you are looking for
but anyhow, you need to flash another rom (via recovery) assuming you have already rooted because you somehow corrupted the system partition.
Thanks for the reply, I tried using cyanogen's mod but it didnt get me anywhere, I will try different mods but could this be a radio issue? is there a way to check that?
p.s. I did a thorough search of the forums and that's how i did all the things b4 posting but then I got stuck...
Hi, sorry I posted in the wrong section, just noticed what you mean.
Can any of the admins move this thread to q&a (or can I do it myself somehow)?
Data?

My friends phone is doing something extremely similar. He gave it to me to play with to make sure he wasn't mad, and it was actually the phone having issues.
Upon playing with it for a few hours problems started to occur. It would randomly shut off, then not want to reboot unless left sitting. It would get after the ROM screen and then shut off. I noticed that that a quick was to crash it was to start browsing the Internet over Wi-Fi. After a few pages loading and moving around the pages as they loaded the poor phone would just turn off.
Since he is using another phone in the mean time, I got his G1 without a SIM card. I was playing games on it, poking around in applications and more and the phone wouldn't turn off. I wasn't till I enabled Wi-Fi that problems started happening. I'm not sure if the Wi-Fi driver is part of the baseband unit or not but it seems that the more data the phone uses (3G or Wi-Fi) heightens its chance of turning off.
To get the phone to boot again I either have to take the battery our for a few minutes or leave it off for a while. Upon which time it will book as if nothing happens.
I also noted that every time it boots it shows an exception error related to "gapps" and you have to click force quit. His phone is running CyanogenMod 4.2. Also the Home key doesn't function, but this is software related because it can turn the screen on.

Phone freezing more and not waking

I've been on Humble 1.42 for about a month now (please don't look down on me, haven't had time to switch since the drama) and I am starting to have some issues with my phone not waking. At random moments, my screen would refuse to turn on no matter what I do. It does, however, respond to me holding down the power button for a forced power off (hard reset?) Anyhow, has anyone else experienced this at all? I had a feeling it was my xfinity mobile app because I had been getting a lot of errors from it lately even though I rarely ever use it. Should I just switch to another rom or is there any other apps known to cause issues with this rom that I should be aware of?
On a side note, I have been on this forum and obsessed with android for the past year and been doing some serious thinking about making a career change into Android development. Been doing some java tutorials on youtube over the last few months and the such and think I'm about ready to start some real android app development. I credit some of the great developers on this site and the awesome experience at Dreamforce this week as the tipping point. Any ideas on additional resources I should look into?
There are a few things that could be causing this problem(that I'm aware of)
1) You may have sideloaded a "virus" app. I attempted to sideload an app once(will never do it again after what happened..) and it completely BROKE my phone. It made apps unable to isntall, the screen would take FOREVER to wake(if it ever did wake) and plenty of other problems. I tried rebooting and got stuck in a bootloop(boot animation would never end), did a factory reset and everything force closed on me so I was forced to flash the .md5/.pit to go back to bare stock and that finally fixed it.
2) Have you flashed Fuju Tweaks? This exact same thing happened when I flashed it on Gummy2.0, worked fine on Eclipse1.3.1 and even works for a lot of people on Gummy2.0 but it wouldn't work for me.
3) Try reflashing your ROM, that's how I fixed the Fuju Tweaks problem. It might fix whatever plagued your phone.
Just let me know of anything you've done recently and I'll try and diagnose the problem(if I didn't already).
Uh-Oh, a virus maybe? Yeah, I will just reflash later on, and change some passwords while I am at it.
I don't think it was that kind of virus but it definitely screwed up my phone.

Looking to Undo Root and All Customization, Need Help to do So

Ok, so as the title says, I'm looking to completely undo having rooted my tablet, and all the customization I did to it, but I'm having a bit of trouble.
According to multiple apps my tablet is no longer rooted, and I got the stock rom from Sammobile flashed on it, and I have the stock recovery back, but I seem to be suffering from the wifi problem that CM suffers, I know this as I can connect to my 5G wifi as well, which I'm never able to do when the tablets wifi is working correctly, and also even connected I barely have any speed, if even any.
Now I know of the wifi fix you can flash through TWRP, but as I said, no more TWRP, and I don't want to reinstall it, I want everything back to stock.
Now, I know of Wifi Fix's for other tablets, like the Galaxy S4, that you can flash on with Odin, but I can't seem to find one like that for the Note Pro 12.2. So if anyone can send me a link I'd really appreciate it.
And also, I can't remember, but did the Note Pro 12.2 ever get anything higher then Android 5.0.2? Because I try to update it, and it says because my tablet was modified I can't do so. Plus Sammobile doesn't have higher then 5.0.2 but I read somewhere that it got 5.1.1 so I really don't know, any help on that front as well would be great.
Now, you may be wondering why I want to do this, in truth I'd rather have my tablet rooted, I save so much battery life getting rid of all the bloatware. But no matter what I do, there always ends up being a problem with my tablet.
I follow all the instructions given, I do exactly what everyone else does, even having someone walk me through it step by step once, and always it goes horribly wrong.
The first time my Nova Launcher would crash constantly, and then everything else would start crashing with it. Then the second time all my videos would play stuttering and jerky, and the audio would be out of sync horribly, and nothing I did would fix it. And now most recently, even though the tablet it connected to the computer, the drivers always fail installation, and even when they are successful, I'm still unable to actually access the tablet from my pc.
I read somewhere that it may be because I disabled Media Storage, but with Media Storage I have just as many problems, it drains my battery like crazy, it causes things to load up extremely slow when accessed through the computer, if a folder has a hundred files for example, it will take almost twenty minutes for them all to load up, and you can't do anything until they do, and if you try copying something into a folder without going into it you'll just be stuck in an endless loop of copying that never ends.
But without Media Storage everything loads up just as quickly as say an SD Card, so said 100 files only takes a few seconds.
And worse thing it caused, which troubled me for a long time before I found out what caused it, at random the media storage would decide to claim 20gb's of space, saying it was all taken up, when it isn't. And it would keep happening at random times, and at random sizes. Near the end it had taken up every bit of free space I had and didn't change back even after several days which is what led me to looking up what was causing that in the first place.
So as you can see, leaving Media Storage enabled is a big no for me. So as such I'm unable to root and customize my tablet for that reason as well.
Now, before you say how weird it is that I have such trouble, and how you have no idea why it would happen, there is a very key reason, Technology HATES me. Trust me, more often then not when I try to do something that works for literally everyone else it fails for me, like say connecting an Xbox controller and getting it to work on my pc. Yeah, never works even after almost 5 hours of trying. So yeah, technology hates, maybe even dispises me.
So anyway, if you can help me fix the wifi, and the update problem if that's possible, I'd really appreciate it.
Are you able to get it connected to a PC?
There are tutorials on how to go back to complete stock if you haven't tried Knox I might search for what people have done before they take the their device back to the carrier. Many people want to un-root before they give up their old devices.

Is this a hard-brick?

I've had my Oneplus One since the beginning of 2015, up until now it's been honestly fantastic, with very few issues whatsoever, certainly nothing that has bothered me at any rate. That's up until last night;
My phone was lying on my desk next to me with the screen on updating some applications whilst I was writing on my computer - suddenly, it starts to vibrate, one continuous long note, I naturally picked it up and looked at it, at which point the phone turn itself off in my hand. That was unfortunately the last I ever saw of my phone alive. This happened at about 6PM yesterday evening, since then I've tried everything within my power to get it to work. I can't access the bootloader, in order to get to fastboot (which would allow me to fix all my issues by enabling me to refresh the device), nor can I access my recovery. The phone turns on and displays nothing, it vibrates, but that's it.
The phone was running the latest COS13.1.1 update (X1) which I had flashed the day before, it was running the stock kernel for the ROM, the ROM was however rooted.
I know a fair amount about android, I also know a fair amount about the OPO, to me, I think something about the LOGO partition has gone wrong. The LOHO partition being responsible for the images shown in the bootloader, fastboot, splash screen etc.... I'm just not sure how that would have happened.
Either way, I don't know what to do, the one doesn't register to my computer in fastboot or adb , so both those routes seem closed. I primarily use a Mac for my work, I'm yet to try plugging the phone into a PC.
I've submitted a ticket to OP, and have spoken to an adviser who moved my case to a 'specialist', but I'm yet to hear back on that one.
Any help would be massively useful, because I need this phone for my work, and just general communication.
Thanks for reading,
Ben
