Here the the first offical release of Fluff Kernel for the Epic 4G
Ok here are two new versions for you all.One is the performance kernel and the other is the battery saver.Both are using the new version of my initramfs that comes with ChainsDD's Superuser.apk and su binary.So i suggest if you have Superuser.apk installed to uninstall it before flashing either of these kernels since Superuser.apk will be installed in /system/app instead of /data/app.And now for the kernels.Both of these kernels are Rom Manager compatiable and have root in them.
This is the battery saving kernel.Changes to it are:
Both Kernels are updated to DI18 sourcecode.
CPU governor set to userspace you can use SetCPU to set the speed of the kernel if you like although SetCPU seems a bit unstable on anything other then conservative.
Default scheduler set to CFQ
http://www.sdx-downloads.com/devs/skeeterslint/FluffKernel-Epic-V1.0.5B.zip
This is the performance kernel.Changes to it are:
CPU governor set to performance your cpu will always be set to max this gives the best numbers in linpack and quadrant if numbers are you thing.
Default scheduler is set to CFQ.
http://www.sdx-downloads.com/devs/skeeterslint/FluffKernel-Epic-V1.0.5P.zip
This is another battery saver kernel for those who don't want to mess with SetCPU is uses the conservative CPU governor that the overclocked kernels use.
http://www.sdx-downloads.com/devs/skeeterslint/FluffKernel-Epic-V1.0.5C.zip
All kernels have been compiled against a toolchain that is stable on the newest OTA.And all kernels have been built with stock Samsung kernel source with no modifications to the source code all changes were to the .config file.
This zip can be flashed with ClockWorkMod or can be taken out of the zip and the zImage can put used as a replacement for the zImage in the one click root method although this kernel has root built into it.I recommend removing the JoeyKrim root method to not cuase and conflicts.
This kernel still has some Samsung bloat in it this will be stripped out as time goes on.I will also be trying out different combinations of CPU governors and schedulers to see which one performs the best.So please test it out and post your feedback.
Link to the stock samsung source that was used for these kernels.

This is not the kernel from the ota this is a custom compiled kernel it should run fine on any roms that are out right now.I am running it myself with no issues at all to speak of.

All the b usybox applets to setup the the loop device should be there. But I have never tried to use them I will have to check the kernel config to see if the kernel is setup for it.

Skeeter this its the best kernel I have used on my phone to date, however one thing to note is that the version of busy box used in this kernel is not compatible with ti backup so the busy box that comes with ti back up needs to be used.

OK it was still broken but i promise its fixed now.The battery drain probably wasn't cuased by the kernel some people have had problems with android system running away and draining battery but it has nothing to do with the kernel they have flashed back to the stock kernel and still have had issues with battery drain and android system running away on them.

I wasn't implying that the drain was caused by the kernel, I was saying that my battery was draining because JuiceDefender wasn't able to disable the APN because my root access was broken. D/l-ing update now. Thanks again!
Can i use this kernel with noobnl's Andromeda Galaxy v1.0.3 ROM?
Currently running MIUI 1.99 with Matr1x #5 kernel. Looking to flash a new ROM and/or kernel as it's been awhile. There's so many of each that I don't know where to start. My main priorities are stability and speed.
The only other ROM I've used is Cyanogenmod but I had a lot of issues with random reboots. Have these issues gotten better?
Any ROM suggestions? Thanks
Rooted stock with Matr1x. I recently switched back after months on CM7 doing the nightly flash routine. Don't miss it a single bit.

I don't even remember what the stock rom is like. I got cyanogen almost inmediately after getting my phone. Perhaps I'll try stock... what's the best way to go about doing this? Do i need to unroot my phone?

backup apps with titanium backup + factory reset (wipe data/cache/dalvik) + flash stock rom.
here you can find a great collection http://forum.xda-developers.com/showthread.php?t=1063664
you DO loose root by flashing a stock rom, but you just have to re-flash superuser (and maybe cwm if needed). I find the stock gingerbread rom very fast and reliable.
Plus, you'll receive the ICS ota when it's ready
(but you'll need to flash the stock recovery)
Wait another 2-3 weeks and flash ice cream sandwich.

Flash deck 1.3. Really fast stable and great battery life. Its just like stock rom with a few extra tweaks. Has some of cm7 mods without the bloat. Has toggle switches on the drop down and some status bar tweaks but very stable and like I said its close to stock. Running it with matrix 9.0. Give it try.

Sorry man its in the nexus s 4g dev section but i cant find it on the GSM dev section. You can always try oxygen rom which is very similar to deck which I was running before I flashed deck. Has the same kind of tweaks more or less. Was also a really good rom. http://forum.xda-developers.com/showthread.php?t=1285243
give carbon a shot. it's based on oxygen but gives better performance than any rom i've used since getting this phone

I'd suggest NSCollab and a trinity kernel. This combo worked well for me but I caught the flashing bug since getting this Nexus S and now I'm off to try Nexus MV.
you should try superosr rom (AOSP), very fast and include CM settings as well
I've been trying all NS Roms, and I'll prefer NSCollab because,
-Fast and stable (Near 5000 in quadrant)
-Never had a random reboot
-Extremely stable at 1,2GHz
-Probably the best CM7-based ROM
I don't give a opinion about which kernel u need to use, because they are all awesome, for the highest score in Quadrant, use the Trinity TUV kernel.
But I like the Netarchy or Matr1x kernel more because they are more stable in my eyes. I hope this will give you some more information
U can also wait for ICS (IceCream Sandwich), it will be awesome too.
I'd suggest stock rom + stock kernel.
lower quadrant score but higher performance
Oxygen 2.3 with Matr1x
4097 quadrant at 1,3Ghz.
*UPDATE*
Try the Franco.Kernel, tested it, very stable and high performance.
Greets.
Matr1x all the way bud lmao
I am trying to find out why my phone is doing this? Could it be a rom or kernel issue? I am running asop+ 2.2 rom and glados 2.7. Or could it be a radio issue?
Sent from my Nexus S using Tapatalk
Glados has a problem with rebooting while calling
It's a known issue in GLaDOS thread. However, some users get a lot of reboots, some never get one.
If you want a quick fix then try flashing another kernel.
Thanks any suggestions on kernals? I have had nothing but issues with matr1x and now it seems glados is giving me issues.
Sent from my Nexus S using Tapatalk
Known issues with GLaDOS. If you want to stay with GLaDOS, you can try:
-Up the voltage a bit if you are using liveoc (or disable liveoc)
-Don't overclock at all
-Disable deep idle
Or you could try matr1x again and maybe up the voltage 25mV across the board (except for 100 and 200mhz) as it is underclocked by default which your phone may not like. Otherwise i'd be trying netarchy, eugene's icup or francos kernel.

I'd suggest you start with Eugene's kernel (ICUP) because I have used it for a week without a single reboot
Disable deep idle, fixes most problems.
99 problems but a deep idle ain't one.
I switched to icup and it seems to be doing good. Thanks guys. I never had deep idle enabled so that was not my issue

I'd try to upgrade to ICS or reinstall the ROM. Also check your battery. It it heats abnormally, that might be the issue as well...
Aosp+ 2.2 is ics... but regardless changing kernels fixed the issue.

Did you try to have prolonged phone calls as well? That's when it crashed... Every 3 minutes or so. The rest is perfectly fine...
I have skyics 7.4 running great. I just flashed faux 10m kernel and bam my auto rotation is reversed. I meant when I hold phone in portrair, it display landscape and vice versa.
Anyone know how to fix this issue? I tried to search but couldn't find a definitive answer. BTW, I have ATT skyrocket phone.
Many thanks
It sounds like you don't have the correct kernel for the Skyrocket. Is this the Kernel you are using?

If so, that is the same combo I am using with no issues.

Now I'm doubtful. I might have downloaded a wrong version. I re-downloaded from link above and now works like butter.
Deep sleep helps so much in lessening battery consumption. Any other good benefits from faux kernel?
Many thanks esp seanz and faux for awesome ROM n kernel.

Underclocking and undervolting
I have synergy 1.3 right now on my phone. Have rooted and flashed this rom with no problems so far by following what I have read on this wonderful site. I would like to try and flash Imoseyon's leankernal. I have read that this works extremely well with synergy's 1.3. I have been following the steps from this guide > http://forum.xda-developers.com/showthread.php?t=1762709 and I have installed ez recovery. So couple questions.
1. I change the recovery to CWM 6.0.1, then hit the flash button and then the reboot recovery button?
2. will flashing a kernel change any settings on my phone for instance I am running apex launcher pro have everything set up the way I like it will all be the same after reboot?
3. is wiping cache/dalvik necessary? I have read elsewhere that when flashing kernels it is not necessary at all?
thanks!
1. Yes. I selected the 6.0.1 from the dropdown and then flashed it. I then made a nandroid and tested restore. I came from twrp 2.2 and wanted to make sure it restored fine.
2. Flashing the kernel will not effect your apps.
3. I didn't but it won't hurt clearing caches.

Oops. Should have mentioned that. I found out that if you get the kernel from his "latest" link it is the 12 version and not 12-2. I posted in the rootz thread about that but it likely got buried with the problems peppe are reporting about using the kernel with 1.4.

Yeah they need to update that link I had actually read about it earlier when reading through the posts but forgot about it last night when downloading the initial link. So far so good. Very smooth haven't had a chance to test batter life will do that at work today giving it a full charge this morning.
Here you go. This is my battery life on 1.3 with the lean kernel and the app CPU sleeper. When I go to sleep I under clocked it at 384 ghz or something like that..then over clocked at 1.7 with the on demand govener and the I/O set to so..this is by far the best battery life I've gotten.

That's pretty good battery life there! What are you underclocking? Min and max or just the min? What are you using to set your CPU clocks? I've been using RomToolbox. I have thinking about dropping the coin on SetCPU, but want to make sure it's what everyone is using to get this great of battery life. Sorry to thread hijack. I've come from a DX and didn't mess with these settings that much.
