Any reason to change kernels in CM10?

I'm running CM10 nightly, and wondering if I will gain any performance improvement (without OC) and longer battery life if I flash one of the alternative kernels on XDA (looking at Devil and Semaphore as those seem to be the most popular)?

yes and yes, but it all depends on how you configure the kernel options and how you use your SGS...

yes, definitely!
but to get the "best" result, of course you have to let it settle for atleast 3 days..
here is a youtube link on how to flash them: http://www.youtube.com/watch?v=kCBN-_zu5cY
i hope this helps,
cheers

Thanks for the answers. I was hoping for recommendations, do you have any?
Semaphore is looking good to me. Opinions?

I'd go with semaphore for ICS...
But for CM10 I'd use Devil..
But that's just me

If you want stability then semaphore.But if you want more tricks to make your phone even faster it is devil of course. There is one more kernel to try Mackay.
Test each to get the right one for you.

Semaphore is the one you need .
What else from having great speed with stability. Yeah, maybe Devil could provide some more speed, which is unnoticeable, for me at least.( except the benchmark tests )

Sema is the most stable one.
But devil isn't bad too.
Try them. But give your phone about 5 minutes after flashing and don't be frustrated when it's a bit laggy after first reboot.
Last days I tryed makay. --> I prefer sema

I prefer devil. My phone still lasts a whole day (7am - 12pm) and is much faster. I like all the options.

On JB roms i always use the devil kernel even if the Semaphore is a very good kernel, Devil kernel allows me to entirely use my phone's habilities with no more battery drain than Sema

you will instantly notice more speed and smoothness with flashing semaphoer kernel.
+ more speed if you set up liveOC to 114%

Does anyone have any links? I'm using CM10 nightly and need a kernel so that BLM and Voodoo sound will work. I tried the latest semaphore 2.8.0 via Odin but the phone would not boot.

You should read the description more carefully. The 2.8 kernel is for JB 4.2 not CM10. Flash the 2.6.5 kernel.

I have few more questions...will i flash only kernel or i need to flash the rom together with kenrel...and can i use odin to flash kernel?Sorry for all thease questions im noob guy in this area

You don't have to flash a rom if you're happy with the one you're using. And you can download .zip's and flash in CWM if you like, but I've found that the only times I've ever got into a boot loop when flashing a kernel are by doing it this way. Not that it has happened often. But for that reason, i prefer to flash my kernels .tar in odin, I've never had a problem doing it that way, but whatever way you choose to do it take a nandroid first, just in case.

Glad to hear it. No problem
Download semaphore manager app if you haven't already done so. Also, if you used the (s) version, you need to make sure and select the bigmem option in semaphore manager and reboot for settings to take effect. Then you have 403MB RAM.

Flash a Semaphore kernel designed for ics. See http://www.semaphore.gr/homepage/semaphore-ics which also has links to xda-developers.

I downloaded Semaphore_ICS_1.3.0. That's all i need, right ?
Just choose this file on PDA and flash ?
EDIT: I already did that and worked.
Only 1 thing: after flashing, i had to push the power button to start ... didn't had to reboot after flash ?

Semaphore 1.3.0 is the one you need. You can flash it through Clockworkmod recovery, its the easiest way. Don't forget to wipe cache and dalvyk cache before flashing a new kernel. Besides semaphore you could also try devils kernel 1.0.3. It is more performance oriented. Flash the one you like. The only thing I don't like about semaphore 1.3.0 is that wifi tethering doesn't work.
Reboot after flashing is crucial, but if you have the new semaphore configuration app, you did it right! Just reboot one more time to be sure everything works alright.

devil kernel

hi....im currently using slimbean 2.4 as my ROM and semaphore kernel. those rom is fine and works. but because i like devil kernel so much...im tempting to flash devil kernel to my phone. the question is, is it ok if i flash devil kernel on my phone with slimbean rom...?and if it ok what version of devil kernels that suit my rom..?
thank you so much for your advices.

I am actually more confused! I am using Cm10 and currently on the stock kernel. I am hearing that other kernels would actually make your phone faster. SO i am really confused which one to get and how would i find the differences between stock and custom kernel?

Just read the developers-thread about the kernel you want. there are many people who have already tested the kernels and tell about their experience!
Hope to have helped!
Edit:
cm10 and slimbean are Jelly Bean Roms, so you can use devils JB-Kernels. Latest should be 1.5.2.

Just search and read. There are many guys that stood on the same edge as you are right now. You don't have to ask again in a forum when they already answered it for another user.
My suggestion: Read about the recommended kernels in the slimbean thread and flash. Or just try on your own. BUT ALWAYS MAKE A NANDROID IF YOU'RE NOT SURE ABOUT COMPATIBILITY.

It is the best friend of every flasher!
But be sure to restore it with the same clockworkmod version. For example: Can't restore a cwm6 backup with cwm5 or lower...cause the system changed.

Just install Hellybean (follow method as described and remember to backup your apps). Based on CM10 with Devil Kernel - its awesome.

Which kernel you are using?
you may try this,
1) reflash the rom with full wipe.
2) if you are overclock the OC clear int.d and NStool setting or using kernel cleaning script
note: only use one kernel setting apps ( e.g NStool , semaphore manager and +++)
If you are using semaphore kernel try not to use NStool setting and semaphore manager.
Hope this will help. :fingers-crossed:

i think the problem is the app of the sim card, because sometime it disappear from the drawer. This app is named "kit strumenti sim" (in italian) and is a default app...

I kinda have a similar problem with the OP. Except, my SGS (running CM10.1) only random reboots if I'm using another kernel, other than stock (mostly, I tried with Semaphore, diff builds). Any ideas anyone?
I would really like to use Semaphore, due to its deep idle and other options.
Sorry if I off-topic'ed here!

if you flash semaphore kernel(2.9.++ is for 4.2.++ ROM) and reflash the cm10.1 rom yor kernel will change to cm10.1 stock kernel.
so the step should be flash the rom and reboot to recovery and flash the kernel you like. for me flash a new kernel i will clear the NStools settings and init.d directory from advanced clear before i flash any new kernel.

TouchWiz Rom question

i always used OASP ROMS mostly of PAm very good but now i did see a touchqiz rom online with multiple windows support etc. I sure wanne give it a try. Does anyone know which ROM is stable and safe wiht futures like this:
Also, im on ParanoidAndoird with PIE, and on utackas kernal. Can i just wipe rom and flash trough cwm or is it safer to get back to GB and then reroot and thenm flash with cwm?
thnx in advance

utackas and cm kernels are safe. Try Ultate XXLSC v.5.1 by joosh3.

mm had my eye also on that rom, seems good, pictures added and updated frequently, so just do full wipe cache dalvik and install this rom? then flash philzz?? or stay at rom stock kernal? im pretty new with touchqiz roms and i also not sure if XXLSC can be flashed on my n7000? does it have any reason why that is in the title or can i just flash?

The kernel you're flashing before installing Rom doesn't matter since with v4 will be replaced by PhilZ 3.1 for XXLS7
