Hey guys... Just rooted my Nexus 7. I did some research on kernels and found out the two most popular ones are motley kernel and trinity kernel. Can you please explain the differences among the two and which one is better? Thanks a lot..

I've tried the available kernels a few different times and I personally like Faux's kernel most of all. It's nice and smooth like the others but runs quite a bit cooler for me when gaming.
http://forum.xda-developers.com/showthread.php?t=1804374
When I first joined this forum I flashed whatever was the most popular. Those are not always the best.
Why don't you flash them all and see which one works the best for you? Some kernels get you a few hundred points more on a benchmark, but no real difference in every-day usage. I am currently making my rounds of the kernels, currently trying Faux's latest ES Beta build: http://forum.xda-developers.com/showpost.php?p=31508178&postcount=421. Rolling with AOKP Official.
Hi,
I tried Faux Kernel, Trinity kernel and Mothley kernel. Wich is better hmm.
- Trinity Kernel : My device is just not as smooth as the stock kernel. Disliked.
- Mothley : Much smoother then Trinity Kernel but still hard to say if it is more then the Stock.
- Faux Kernel : It is not slower then stock. It is as smooth, maybe even more ?
I'm using cm10 4.1.2 and I am having a lot of trouble with the kernels I have tried. Is/was there a stable kernel with overclocking ever released by a dev? I've tried faux's, clemsyn's, and mkernel and I have had no luck with any of them running smoothly. Also, do 4.2.x kernels work on 4.1.x?

try trinity kernel. but cm changed some stuff, so its possible that many kernels wont work with cm unless its specifically built for cm support.
I unlocked, rooted, and flashed my nexus 10 only a few hours ago.
Now I have a question, about the Kernels, which are available for the Nexus 10.
Are they worth flashing, and which one is good concernig battery and performence.
I use PAcman Rom
I've had excellent luck with ktoonz manta kernel.
From my S-Off DNA
I second ktmanta, but would encourage you to try them all. Trinity is good for noobs, its stable, fast, and there's not much to mess up. Ktmanta with ktweaker is crazy customizable, but if not careful, you can make performance worse.I've readgood things about franco's kernel, but I've not personally tried it.
Here's a good link to learn: http://forum.xda-developers.com/showthread.php?t=1369817
thanks,
i think i´ll try ktmanta, because i have very much experience with kernels on my sgs2 so i´m not a noob
i also read that FRanco kernel is good, maybe i´ll try.
The one issue with Franco's kernel on the Nexus 10 is that it hasnt had much development so there isnt much to it. Basically a few little patches and adding boost pulse to OnDemand governor and that is it. If you are going to run a flash and forget kernel then Trinity is a much better choice right now.
I'm curious what everyone thinks the best Recovery is for the Razr M and what are the best kernels as far as functionality, battery life, and speed.
I haven't played around with installing custom kernels and ive been using the CWM recovery on my razr m and im currently running the AOKP custom ROM.
Dead Calm, arghhh kernel

I think cwm is better than twrp but I am prejudiced by having wiped my extSD in one of the newest versions. See my signature link for an older BETTER version.
I like TWRP 2.6.0 and I had been having great performance with Carbon ROM 1.8 running the arrrghhh kernel. Currently though I'm having issues running arrrghhh kernel with the Carbon ROM 4.3 nightly (runs smooth with the provided kernel) and yes I did use the CM 10.2 version. I'm sure this will sort it's self after a few more updates.
***edit***
as of 8/16/2013 the arrrghhh kernel and carbon rom nightlies now work together properly

When installing a custom kernal, do i have to take any special steps such as wipe dalvic etc..? Or simply just flash zip from cwrm?
Making a backup and wiping cache and dalvik are always a good idea.
So I was running stock for a very long time, and I had insane battery life. I usually got 5 and a half hours of screen on time with my usage which mostly included browsing and a bit of youtube-ing and maybe the 30-40 minutes of gaming. I never used it conservatively though, I just didn't need anything else. I had GPS and bluetooth off and I used WiFi only at home (2g, not 3g, when outside).
Anyway, a month ago I flashed PA 3.99 and my battery life has reduced. I only (relatively) get 4 and a half to 5 hours of screen on time. Is this normal? I thought I'll get better battery life with a custom ROM. I'm still running stock kernel BTW.
PA is giving me too many issues including random reboots so I've decided to flash either CM, PSX, Carbon or PACman (help me in deciding from these?). Should I flash a custom kernel too? I'm leaning towards Faux for the battery life but I'm scared it might reduce it!
PS : I just flashed the PA ROM, so I'm still running the stock kernel, right? The thing is, on my older phone, some devs bundled the ROM with a custom kernel. My kernel version says 3.4.0-perf-g04b6fae. Sorry for the noob-ness.
There are just too many factors, the coding, apps installed, kernel, optimization, the user usage pattern, signal quality. It wouldn't surprise me though, but if it work for you stick with it.
Kernel alone doesn't determine the whole picture. I don't use PA, but I don't think it use stock kernel since stock usually ends with "mtv.corp.google.com".
You can check these battery life benchmark for kernels if you want to try, however, I don't go by them: http://forum.xda-developers.com/showthread.php?t=2449982

I did exactly the same, and feel exactly the same... I have the same apps, same usage, and I feel like I have a few hours less with this ROM (and same Kernel). I'm planning to give Franco a try, I think, although according to that benchmark it won't give a great battery life either... Have you already tried anyone?
Just a noob question, I haven't yet completely understood that thing about builds. When I was completely stock I was in JWR66Y. Then I only flashed PA 3.99 RC2 (for that build) and now in settings it says JLS36G. It now means that I have to care that kernels get on well with JLS36G? I thought I would stay in JWR66Y.

there are two versions of 4.3..one is stock (JWR) and one is AOSP (JLS)
the AOSP build is more latest in a way..AOSP build has more speed but has random freezes for 2-3 seconds (should be fixed in most of the roms by now) while stock JWR build is not as speedy as AOSP but doesnt have those random freezes.
And yeah you would now have to flash a JLS kernel rather than JWR..and if you want a kernel with good battery life..try hells core kernel which IMO has the best battery life and performance

after trying multiple different ROMs, kernels, etc.. I found that I wasted a lot of time getting geeked-out over nothing special. Sure, it's fun.. exciting... learning.. some minor features that are cool.. but, I do desire to have those hours of life back. Also, I experienced many more downsides than positives. Battery, lock-ups, random reboots, etc. A rooted stock device has served me very well..

Thanks! I had read about the difference between AOSP and stock, but didn't know/remember that JLS always AOSP. I think I felt this one better than stock. I've already been 4 days with it and I'm really comfortable being able to change dpi individually, custom it and use Pie, too, and stability is just as in stock, I think (I only got restarts in both of them while using Skype :S ). I didn't even worry to try CyanogenMod (in all my previous phones I had used it, always).

That's my concern in trying with new, custom kernels. Right now I'm just fine (although I'd like to have a little better battery life), so I'll keep reading and see if it's worth changing the kernel .
Thank you!

the hassle come with flashing a new rom because you have to do a factory reset..with kernel though its pretty simple just wipe cache/dalvik cache flash kernel then reboot. So just try the kernels you think are interesting and if youre not comfortable with it then flash another one..i know its a hassle with rom but not much with kernel.
P.S you guys should really try hells god kernel. Ive been personally using it for 3 months and the battery life is just amazing
I'm getting good battery life with KitKat.

Yeah, I've already flashed kernels in other phones, but never had this risk of compatibility issues due to different builds.
I've read that JSS kernels in JWR roms cause problems. Is the opposite not true? I mean, right now I have a stock JWR kernel running in a AOSP based ROM (JLS). Could this compatibility problems cause boot issues too? Of course, always with tested kernels. Or I'll always have the opportunity to boot into TWRP and flash a new kernel, until one works?
And one last question. When I look for AK's 4.3 kernel I only read JWR and JSS. Why doesn't it say JLS? Is it the same as JSS, then?
Thanks!
I can vouch for the above statements. I'm liking Hells core kernel. It's fast and has great battery life (as good as stock, maybe even slightly better). FWIW, I'm using Carbon ROM now and it's MUCH better than PA.

Sorry i forgot to mention that JLS and JSS are the same build JLS being the latest one..so there is no difference in JSS or JLS. You can flash a JSS kernel on a JLS build no problem. But if youre build is jwr then your kernel build should also be jwr because yes it causes compatibility issues if you flash a jwr kernel on a jss/jls build or vice versa. In every ROM the stock kernel is matched with its build number. If its a jwr ROM then the stock kernel would also be jwr and vice versa.
Flashing a jwr on a jls/jss rom or a jls/jss kernel on a jwr rom might cause the phone to be in a bootloop (not going past the bootanimation) and even if you get it to boot up the performance would be lacking and it might cause random freezes, graphic glitches and or random reboots.
However there are some roms that are a hybrid which means its a combination of jwr build and jls/jss build. In that case you will flash a jwr kernel only nothing else.
