Ok so to make a story short:
I installed CM10 M2 wednesday, everything went AWESOME. Smooth, responsive, fast! Pure JB awesomeness. Then, satuday i decided to flash Faux123 kernel to have additional governors and from that point, everything has been terrible. The phone has been extremely laggy, it randomly rebooted and sometimes when i turn off screen, it doesnt want to turn back on and i have to battery pull.
Since that, i have formated the phone at least 5 times, i tried just a factory reset, complete wipe through CWM, reflashing rom, but nothing worked. What really weirh though is when i reflash the rom, and reinstall all my apps and put everything back, until i reboot the phone once, the phone is smooth and stable. But as soon as i reboot the phone, i'm done. It becomes laggy again, reboots and has sleep of death.
I'm really perplex as to what can cause this. I honestly am just about to ODIN this phone back to stock and just wait for official JB...thats unless somebody here has a quickfix?
I'm assuming when we reflash rom it also reflashes kernel, maybe reflahing just the kernel will solve this? anybody got a link? or a kernel to suggest?
EDIT: Now i can reproduce the problem. Everytime i turn off screen and i turn it back on shortly after, it reboots
Try ktoonsez kernel. He seems to be putting more updates than faux. Faux hasn't updated since August and ktoonsez updated 5 days ago.

No he does update his kernels he just doesn't update them on original thread. My build version is Oct 13th. But ktoosez has cm10 kernels?

I managed to isolate an issue, this issue is present when i use any other governor but On Demand. As soon as i switch, the phone starts to lag a lot and crashes

And yes, ktoon has TW and AOSP kernels for ICS and JB.

I agree with d3athsd00r, Use ktoonsez kt747 kernel. Im running CM10 M2 as well and everything is fine for me, especially a significant improvement in battery life

Ok, i've just installed Ktoonsez kernel. I have changed to different governeors and i've yet to have seen any lag. Thats a great sign. Juste one question though, what combo of governor + scheduler gives the best battery life?
bump
I use ktoonservative and bfq, but there is no "best" What works best for someone else might not work well for you.
Testing is the only way to answer this for yourself.

Hello all,
I recently purchased an S3 and just trying to figure everything out for it (as I am coming from the nexus where everything is much simpler) The only real question I have for everyone is, What kernel is the best so far? Something that is optimized for battery life and speed.
If anyone is from the Nexus development you would know about Franco's kernel which has served me well for a long time, So what I'm looking for is something that is like the Franco Kernel, and has customization settings.
Any insight would be great
Cheers.
When running an AOSP JB ROM (like CM10 or AOKP), I'd suggest ktoonsez's KT747 kernel. It supports overclocking to 2.1 GHz, undervolting, comes with numerous tweakable governors and io schedulers, and it comes with its own adjustment app called KTweaker which is very handy. Just don't use SetCPU or Voltage Control or any other such app with that kernel as they could cause conflicts with KTweaker.

The current KT747 for Sammy ROMS seems to be having issues with many phones though, so for Sammy ROMS I'd say your safest bet is faux123's kernel. http://forum.xda-developers.com/showthread.php?t=1785466
Much appreciated. I was seeing ktoonsez's KT747 kernel, and figured this was the "main" kernel for the s3 but I just had to know for sure. What you describe with it is exactly what I'm looking for in a kernel...full control of it. Thanks again
Also on KT747 ktoon created his on governor called ktoonservative. It's based off conservative but it's kicking some serious butt with my device :good:. I'm also severely under-volted but that shouldn't really change much as far as battery life.

I tried the kernel (both actually) and had no luck with either, one caused everything to fail ie: wifi, data, launcher, touch screen was unresponsive. And after flashing in the other one that says it is 100% stable on all devices, I was left with a phone that wouldnt turn on, and when it did start up, the screen was unresponsive. I tried clearing caches, fixing permissions, but nothing worked at all.
So I went back to stock kernel. Hopefully some of these issues can be resolved some day.

Are you sure you flashed the correct version? Both kernels come in ICS and JB flavors.
Also, I haven't seen anyone else with this issue so I'm not sure what happened.

DAMN I MISS FRANCO KERNEL!!!!!!! It was on the note n7000 in a way I wish it could come to the S3
I am running aokp 4.1.1 build 3 and I love it. I know the rom is still not stable, but I keep getting sod regarding the fact that some people don't get them that don't get them. Tried reflashing, switched it to interactive and minimum frequency. I know the rom is still not stable, but there's got to be a soultion to this
If there was a solution then it wouldn't be happening would it.. try upping your lower freq, try a different governor and scheduler.

Can't believe you said that there's got to be a solution.. Why? why does there have to be one.. stuff happens and people more knowledgeable than you or I are working on it. Hey honestly I don't get them on either AOKP or CM10. You have a choice though cm9 or aokp ICS run great and maybe you should try them until things meet your standards.
Sadly, I do not have enough posts to my name to reply to the thread in the Development forum, so I thought I'd post this here. I'm using Drew's JB747 M7, and it's very close to perfect for my needs. I had a couple issues that I ran into, and I've fixed them, so I wanted to share.
1) I ran into the issue with the Call Log prepending + to all incoming calls. This, of course, makes it impossible to return a call by tapping it in the Log. The TMO RIL files mentioned in post #3951 in that thread did, in fact, fix the issue for me.
2) Even after updating the RIL files, I found that I could not use Google Voice for my voicemail. I know that it's not possible to use Voice's built-in setup wizard to configure itself as the VM service in TW ROMs, and I know that I cannot get VMs to display in Call Log with TW either, but the issue I had was that my forwarding did not work. If I rejected a call, it went to dead air. It did not hang up, and it did not go to my GV greeting. After some tinkering, I found that resetting my forwarding numbers to the default (using the MMI ##004# in Dialer) did work with call rejections (sending to my AT&T VM, of course). After doing this, I tried the *004*[GV NUMBER]# MMI, and tested the call reject again. This time it forwarded to GV as expected. I know this is mentioned as a possible fix in other threads, but I wanted to state that it worked for me, so it's worth a try if you already have GV as your VM service on whatever ROM you're flashing from.
3) SOD - after freezing some Samsung bloatware, I rebooted. I'm using the stock kernel DG includes in the ROM. A couple hours later, I experienced my first SOD. The soft buttons were illuminated, and the only thing I could do to fix was pull the battery. This was with the suggested settings in No-Frills from the M7QuickFix set, and supposed to apply on Reboot. Looking at the CPU speed stats in No-Frills after the SOD, I noticed a whole lot of time spent at 384MHz, despite 486MHz being set as my minimum. It seems like perhaps No-Frills settings are not, in fact, re-applying after reboot. I'm still tinkering with No-Frills to see if I can replicate.
I may flash Ktoonsez's kernel so I can get KTweaker instead, but wanted to at least mention that it looks like double-checking CPU speeds after a reboot might be a good idea.
Hope this helps someone out there. And a big THANKS to Drew for his great ROM. Donation heading your way shortly, and I can't wait to see 1.0. :good:
Flash ktoonsez kernel it fixes the sod with out needing to set min to 486

Just flashed ktoonsez's 10/31 kernel, which was posted moments after I'd finished flashing 10/28 . I ran KT's kernels on all of the AOKP and CM JB ROMs I've run, plus a handful of TW ICS ROMs. Love KT's work, but wanted to try out the stock kernel in JB747. I was getting fantastic battery life with the stock kernel, so I'm hopeful KT's gives me some good life, too.
Flash grafixxnyc port and u won't have any issues.
As for your Google Voice issues i never had issues. It would say it didn't work when setting up but always did.
I was a fan of Drew's ROMs but the high Android b system drain was b worrying me. After 6 builds it was always high.
Been running this port and couldn't be happier. Try it you won't be sorry.

Thanks for the suggestion. I actually have tried grafixxnyc's Stock Sprint port and prefer DG's ROM. Too much Sprint stuff in grafixxnyc's port.
I have not, however, tried BlackJelly if that's the one you mean. Was considering trying it this weekend, though I'm hoping Drew will have JB747 1.0 out by then.
At this point, JB747 M7 with KT's kernel is working quite well for me, after the RIL fix at least. Going to keep this as my go-to nandroid for a while I think. :good:
Thanks for the tips. Im currently using m4.1 sprint leak as my daily driver. Works great, I get over 30hrs of life with light use. About 18-20 w mod use.

Yeah, I was getting great battery life with DG's stock kernel. KT's kernel eliminates the SOD for me (so far...it's only been 36 hours), but the battery life is slightly inferior. Using ktoonservative and SIO. Stock voltages, so I may need to play with that.
Which specific ROM are you using? Got a link?
Hi,
My GN was fine when I purchased it a month ago, brand new, but its so sluggish that its almost unusable. Phone dialer, Messaging and almost all apps load with a 3-5 second delay, even the keyboard opens after a few seconds.
I'm on stock 4.2.1 (deodexed) and even flashed fugumod kernel just today hoping it would fix things, I even factory reset it but no joy.
Could it be a hardware issue? is there any way I could run some quick tests to see whats wrong?
A similar thing happened to me when I decided to try a new kernel I've never used before, and it did not agree with my phone. Try a different kernel like lean kernel or Franco kernel and see if it still happens. If so, go back to stock.

I was on stock, then tried FuguMod, but it still lags, not as much as before but pretty slow.
Do you have lag spikes? Like many little freezes?

Exactly, many little freezes
I have thr same problem...from like 30 to 30 seconds I have those many little freezes...i tried many roms/kernels but no succes,even flashed the stock images and it's the same...I think something is messing our CPU cuz i had this issue even on stock rom/krrnel

What are your kernel settings?
why dont you flash to 100% stock and see if the problems still persist?
Franco's kernel always good. I gave my gf my gnex never had a problem with sluggish she loves it.try going back to stock and redo everything start fresh and see if it still persisting

Just stock...should i change anything on the gov settings? Or the voltages? It seems that my device won't support some kernels. If you could tell me something to change for making it better,that would be great.
Have you used up almost of your memory in the sd card? I don't know if GN's are affected by eMMC bug brick. I've asked this before but they said GN is not affected. It has something to do with a bad chip.

Wel, I was having pretty good battery life with the L710's stock MA6 ROM with KT747's kernel but I decided to flash a new ROM.
Here is what battery life looks like and I'm worried that its not the ROM but a problem with my battery, since people have been reporting exceptional battery life with this ROM.
Some specs.
ROM: LIQUID-JB-2.1-STABLE
Kernel: KT747-Kernel-AOSP-JB-MR1-SPR-03-14-2013
Governor: ondemand
Scheduler: cfq

Attached is the battery screenshot.
It won't even charge when connected with light use. Thoughts?
Before anyone asks this is my third time installing the ROM and I'm pretty sure I don't have the Google services wake lock.

O the three times u installed did u do a full wipe (wipe data factory reset ) also are you over clocked and did u restore old kernal settings.

I try to never dirty flash and usually just restore apps from TitaniumBackup. All three times were full wipes formatting any partition I could other than extSdcard. No old kernel settings were restored and I'm not over or undeclocked but I did under volt by 50 and the phone seems stable but no improvement.
As a matter of fact during the latter of the installs I restored nothing. I've also disconnected my sdCard in hopes that it was a bad card (some hopes) but to no avail.
I am redownloading the rooms even do the md5 sum was the exact and downloading the gapp from a different source.

Try running LiquidSmooth's stock kernel. I'm getting pretty good battery life with that. KT747 may not agree with your phone combined with this rom. I had good results when I ran KT with a TW rom, but not so much with AOSP. Every phone can behave differently.
Good luck.

I ran my phone with the kernel that LiquidSmooth has as stock, and it was extremely buggy for me, maybe it just did not behave well with my phone but it looks like the kernel has a few known issues as is. One bug I had is that audio playback was extremely erratic, and I haven't come across a commenter stating anything similar. I'd really hate migrating from LiquidSmooth, especially with the notion that I just "gave up", and not on just any release but on a stable release.
Update:
Update:
On this new install from a new download and gapps from a different source, I do not seem to be having the audio issue, which seems strange as both prior downloads had an exact md5 sum.
*Currently hopeful with fingers crossed*
I'm really enjoying LiquidSmooth, too, so I know what you mean. I hope it works for you this time.
