Ok, sorry if this seems like a stupid question but... I have flashed/tested all of the Tiamat Kernels onto my xoom and it seems that I can only run the 1.4 Ghz Kernel with no random reboots. So I thought that if i download the higher 1.5Ghz or the 1.6Ghz and just under-clock it to 1.4Ghz that should stop it from doing random reboots, but sadly it doesnt and I still get random reboots even with Setcpu Under-clocking it to 1.4Ghz. Now is this typical or am I missing or misunderstanding something? Is there a reason why I cant use the higher Kernels and Under-clock them to 1.4Ghz and get no random reboots? I am only asking because I flashed the Riptide and under-clocked it to 1.4Ghz and it really made my xoom feel much faster and nicer in my hands and would love to keep using the Riptide Kernel.
Thanks in advance,
-Dez
I have the same issues and have been wondering the same thing.
I have similar , with 1.6 with ums
only flashed to get ums , and had a few crash/reboots for the first time since i bought my xoom about a month ago.
what i could do with is a stock speed kernal with all the bells on !

I too have noticed this, after reading your post I tried keeping the Kernels but with no OC and left it at 1.0Ghz and it still has random reboots. So is there something in the Higher Kernels that are causing it to be unstable regardless of what Ghz you clock it to?
watch setcpu at times. It doesn't matter what you set the clock at in setcpu it will still go to the max clock the kernel allows. I am not sure if it is a bug with setcpu or if it is just the way the kernel works. If you reboot your Xoom when setcpu is at 1ghz, then go and play with the xoom after reboot for awhile. Go back into setcpu and look under the info tab. You will see that the cpu has indeed been running the higher clocks then 1ghz at times. It doesn't run those higher clocks much but it does. Which is most likely why you are getting lockups or reboots. My Xoom seems to love the 1.5ghz kernel but hates the 1.6ghz one.
Funny I was on the same boat. Started out with 1.6...reboots. went to 1.4 no problems. Tried riptide. Got app force closes. Now on 1.5...stable once again. The thing is im not even using OC on any of them

I have a US Wifi Xoom and I recently flashed a AOSP OC Kernel and I'm scared that my Xoom will mess up. Today I unplugged my Xoom and it shut off by itself. I couldn't turn it back on the normal way. I had to hold volume up and power. I have a feeling its kernel related since I flashed it last night. Thanks.
For the US WIFI Xoom, follow the instructions on this thread to return to stock:
USA WIFI 3.1 Stock:
http://forum.xda-developers.com/showthread.php?t=1080963
Pretty straight forward.
Just out of curiosity, which OC kernel did you use? If you're pushing to 1.6GHz, it may not be as stable as others. There are others - 1.5GHz and 1.4GHz that you can try for more stability.
Tiamat's 1.4.2 Kernels:
http://forum.xda-developers.com/showthread.php?t=978013
Keep in mind though, these kernels are tested rigorously before deployment, so unless you decide to mess with the files themselves, you shouldn't inflict any harm on your XOOM with these Kernels.
I did the 1.5 kernel and I just found it weird because I saw a thread today about someone's Xoom not turning on.

Hello,
Is that possible to have an added kernel to theTiamat list: one without any OC?
Battery consumption is a big concern for me...
Sorry for the post in here but I'm still limited to Q&A on XDA.
You don't have to overclock even though you flashed an oc kernal. I have 1.6 oc and I don't oc at all.
Is there an option to turn off overclock or is the kernel supposed to work with SetCPU or another OC app?
If OC isn't set as default then that's a good thing because I don't see any advantage to overclocking the Xoom.
It was a scare and I don't want it to happen again. Is prefer the stock kernel to avoid any problems.

The OC isnt set by default. It is still set to the default 1GHz.
The kernel just allows you to overclock to 1.6GHz if you wish.
I had another weird reboot yesterday. The last thing I flashed was the kernel.
Might do that sometimes. Might be whatever you were doing. Or the xoom isn't used to the kernal, or just plain don't like it.
Just a quick question for you guys: I recently purchased an Infuse from the marketplace here, and so far I've gotten an absolute TON of lag using the device. I've flashed Infused 1.5 and Bionix with the Infusion kernel, and so far the lag has gotten better, but it's not totally cleared up. I'm definitely not new to Android, but I haven't seen anything like this before. I know that Quadrant isn't a reliable benchmark, but I'm scoring about 1900, OCed to 1.5Ghz.
Just to give an example: I'm using desktop visualizer to add some custom icons to my screen. When I go to select an icon image, it's fine, but it freezes for about 90 seconds when a list of my apps comes up.
Anyone experience this before? And if so, how did you solve it? If this was widespread, I'd imagine there would be complaints all over here.
Which app are you using to set your overclock settings, how many clock speeds do you have enabled, are you under or over volting, and *which governor* are you running?
I have seen some similar problems here when I was using conservative governor with poor choices of clock speed. Right now Infusion 1.5.2 kernel has some issues with not liking the ondemand governor, so I reduced my number of available clock speeds so it would jump to the top more quickly while using the conservative governor.
Also, did you use either the return to stock, or the ultimate unbrick flash before you flashed your ROM? If it was a used Infuse, I would do one of the above before I start looking anywhere else, then reflash your rom/kernel of choice.
I'm using SetCPU with the OnDemand gov (400/1500), no undervolting. I have a profile set to underclock it to 300/700 on conservative when I'm charging, but that's about it.
I think I'm going to use GTG's unbrick/return to stock and root the thing myself, I figured I'd ask before I did anything drastic. My UI is a ***** to set up every time, and I hate wiping because of it.
Just a quick note, I've had some serious lag using the oc kernel... Like real world usage got worse after oc'ing

Although it is counter intuitive to the way governors should work I have seen less lag on Infusion 1.5.2 when I use conservative. The ondemand governor seems to be having some issues with the most recent update. If you flash back to 1.0 Infusion you get a max overclock of 1.4, but it is much more stable IMHO. Also FFC is presently broken in 1.5.2 and will hard freeze the phone (battery pull).
I'm debating flashing back to community kernel, but I am going to wait and see how long it takes my battery to drain because I am using some undervolting. You might try using conservative governor and only enable 100, 400, (800 or 1000), (1200 or 1300) and 1500. Honestly the infuse is my first smartphone, but I've tinkered with desktop hardware the last 15 years. It literally amazes me everytime I pull the battery out of this phone and feel how light it is.
I also used the desktop vis app and yes it lagged when chosing apps however it seemed to get better after three or four times but that seems to be the only place it lags for me im using the oc-uv kernal 1.0 clocked to 1.4 seems bulletproof compared to later versions im getting great speed and batt life with this kernal but i had the same lag in the same event as you

I'm going to try bringing it back to stock and re-rooting it myself, if only because I trust myself with adb//scripts/rooting, and I'm hesitant to trust someone I don't know. Lag has gotten a lot better since switching to conservative, OCing to 1.6 and undervolting a tad, but it still lags when opening apps or scrolling through long lists. Desktop Vis is of course, still a nightmare.
Oh well, I'll report my findings tomorrow I guess. Hopefully I'll be scoring higher than the 1700 I just pulled in quadrant.

Do you use spareparts?
usually yes, but I dont believe I installed it yet on the infuse. Why?
lag on stock also
I'm 100% stock & get lag also. Definitely in the situation you describe, when the app list comes up for adding shortcuts to any homescreen. Takes forever for that list to come up. Secondly, simply from running for a while, i have to kill all the apps using the built in task manager in order to get it to run smoothly again. It's like it never closes an app. I'm new to android, but guessing this is a problem inherit to android. Can't see how samsung or at&t could have screwed this soo badly to cause it to never close an app. Hoping memory management is better in Gingerbread.
Blario, you're new to Android, so you need to read up on how memory management works with Android. It's not SUPPOSED to kill apps, and that's not what's lagging your phone. In your case, I'd think it was more of a case of WHICH apps you were running.
yeah, the longer I have the phone the more it lags it seems
probably going to push me towards the Evo3D
If you're on stock and after a week or two your phone gets slow as hell (mine did), install a Voodoo lagfix kernel. All the current ROMs include it.

I don't do much. Twitter, "Web" (some mozilla stock ish), SMS, phone, Android Market app (browsing), and Maps. I've had it lag up using only those. Far less often, I use Yelp... that's about it.
Not supposed to kill apps? When I kill them it fixes the problem. Maybe it *should* be killing apps?? If its supposed to flush their state to disk... it seems to be doing a poor job at it.
I would be suspicious of your microSD card (if you have one). Do you know what class it is? Have you tried removing it and performing the same functions in which you see lag?

It's the stock card that came with the phone. Any way to check? The apps are installed to it... so removing it I wouldn't have the apps available anymore.
A little update: I returned back to stock and re-rooted. I installed 3E, then CWM, then threw on Infused 1.5 and Infusion, OCed to 1.6Ghz and slightly undervolted (about 25-100mv along the range) using SetCPU.
As of right now, it still lags on occasion, but not as bad as it did. Quadrant is giving me a whopping 1300 average score, with a low of 800 and a high of 1600. This is just pathetic.
So after being S-OFF and perm rooted, I have found that setCPU is being a turd. While it works when it works, it requires quite a bit of effort to work.
Each time my phone reboots for whatever reason (pitiful attempts at getting adfree to work, ect) setCPU must be uninstalled, then reinstalled, then set back up via command prompt. If this isnt done, it will cause the phone to restart over and over again.
Any ideas as to why this is?
Matt
Because SetCPU doesn't have a profile for the Sensation's processor yet.
Any good alternatives to setCPU then?
Matt
i have the same issue but no fix for OC Daemon, except restoring, flashing and setting the oc to 1.5. if i set to 1.8 it reboots and reboots and reboots and so on.

This is never going to be fixed. Your phone can't handle 1.8 ghz, it's the hardware.

If you flash a custom ROM and want overclock, flash Android Revolution HD. It has OC Daemon and is really good!
You can overclock to 1.5ghz and be quite stable. You can also underclock to about 245mhz when asleep so it saves the battery when it's in your pocket However, as MT4gUY said, right now you can't overclock to 1.8ghz.
@Sdobron As I understand it, the EVO 3D has overclock to 1.8ghz and that has the same processor as the Sensation...? Is that overclock stable...?

This is incorrect. I was overclocked to 1.8 Ghz for the longest time before I decided to go down to 1.6Ghz (what I am at now) for battery reasons. 1.8Ghz was good for getting 3100 Quadrant scores, but that was it.
There must be a way to reliably overclock without a ROM? I dont see the need for a ROM right now. My phone is already fast! I use ADW EX with overclock, and I have bloatware frozen along with Sense frozen. I am perm rooted, but would love to be able to reboot my phone and not have setCPU act a fool.

I recently rooted my P999/G2x and installed CM7.1.0.1, and am extremely happy with it. Am looking to tinker just a *little* bit more, but have some questions... I have LOTS of answers on the forums, but am somewhat skeptical about the currency of some of the information out there (let's face it, stuff changes fast!). So, down to it:
Kernels:
- Did CM7 overwrite the stock kernel?
- I understand the benefits to changing the kernel; what about drawbacks?
- Does CWM back up your kernel with Backup and Restore? If not, how do you do this?
- Recommendations on a good, reliable kernel to use w/ CM7? I am looking at faux123's CM and morific's Trinity. Thoughts?
OC/UV:
- Can you OC on stock/CM7 kernel?
- What is the best app to manage OC/UV? I have my eye on setCPU, cpu Master, and Android Overclock (JRummy16)
- Any recommended settings for the G2x? Any settings to avoid? My plan is to incrementally adjust, but don't really have an idea as to where to start.
Thx in advance!
- Did CM7 overwrite the stock kernel?
Yes
- I understand the benefits to changing the kernel; what about drawbacks?
Since not all the chips are made in the same way, you could soft brick your phone if you try to flash an undervolted kernel. This is the way mine is, and it's somewhat irritating but not all that bad using the stock voltage and overclocking to around 1.4ghz rather than 1.5ghz+. Also, battery life should be expected to be less with an overclocked CPU. It's up to you to decide how you want to run your device.
- Does CWM back up your kernel with Backup and Restore? If not, how do you do this?
Yes, backup creates an image of the entire thing. Before you start making changes, always make a backup so you can revert to previous settings should you soft brick your device. Make a backup, clear cache/dalvik, flash the kernel and reboot the phone. First boot times will always be a little longer when flashing a kernel, so be patient and don't pull your battery right away. For me personally, if it hasn't done anything noticeable after about ten minutes, I pull my battery. Reboot into recovery and restore from the backup you made. If you started off trying an undervolted kernel, time to try the standard voltage now!
- Can you OC on stock/CM7 kernel?
No, and you'll be able to tell once you flash CM7 and use SetCPU (or whatever you use) and see the max is still at 1ghz.
- What is the best app to manage OC/UV? I have my eye on setCPU, cpu Master, and Android Overclock (JRummy16)
Personal preference. I think probably SetCPU is used by most people including myself.
- Any recommended settings for the G2x? Any settings to avoid? My plan is to incrementally adjust, but don't really have an idea as to where to start.
If you want to be safe just start out at 1ghz. If you have no random reboots with your kernel then move it up to 1.1 or 1.2 and see if it's stable there. Personally, I just went ahead and overclocked to 1.4ghz. For the most part people don't really have problems with this I guess. The problems usually lie in whether or not you are undervolted and by how much. If you find your device can run an undervolted kernel, I would just leave the undervolt settings the way they are. As I said, I can't run OC/UV and have to use SV, so I never touch any of the voltage settings.
Hope this helps!
Using eagle blood (cm7 based) with faux kernel.
I heard trinity kernels may have random reboot but don't quote me on that.
Try faux kernel with oc/uv. Its very good, latest is 0.48. But if you go with the ds version (debaouch?) The battery percentages are all over the place... Lol one minute its 50% the next it may be 34%...
Use set cpu. I've uv additional 25mv across the board with no I'll effects. Screen off profile at 503 mhz max and some other profiles will have you getting 24hours easily with normal usage.
Make sure test it out before you "set on boot"...

I tired using DS OC/UV Kernel Version 0.4.8 kernel on my g2x running the latest stable release of CM7 1.0.1. Followed all the necessary step of wiping cache, and darvik but when I reboot, I get the blue lg sign after which the screen just black out and its stuck like that till i pull the battery out. Any one know what I may be going wrong here? ? ?
Trinity ELPmax with Phoenixblood is the best combo. Trinity batterylife is amazing. When i leave the house my phones battery is 100%. 11 hours later (I when i make it home) my battery is always under 60% but never less then 40%. I play music as soon I leave the house, and till I get in the house. I also turn of data when not using and have setscpu set to 900mhz max and screen off profile set to 432 max 216 min.

+1 to everything you said
just to add if you want to over clock then go with faux or trinity. the cm7 kernel is faster then both @1000mhz, if speed is what your looking for without the dangers of oc. The stock cm7 kernel also lacks the ability to under volt soo battery life might not be as good though

Flash cm.
Flash kernel.
It may take a while for the system to boot, 5 min. Let it load, and reboot, enjoy.
