Kernel Troubles - Nexus 7 Q&A, Help & Troubleshooting

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.

[Q] Changing from CM10 to Danik MS2Ginger 4

I´m currently using CM10 by Tezet, and I have flashed the GB kernel that Tezet put in his post. It all works nice and well, but I wanted to try Danik's MS2Ginger. Does anybody know if it works well without flashing the custom kernel from Danik? Can I just keep my current kernel? If possible, I'd appreciate the opinion of someone who has tried this.
Thanks in advance!
PS: On a side note, my current kernel (CM10) is named: 2.6.32.9- Jellybean, etc, etc. I had the impression that the Linux Kernel for Gingerbread (that is to say, the GB Kernel) was 2.6.35. Why keep the froyo kernel number?

I think you can keep your kernel but you would really benefit from the new one when using Danik's ROM. I haven't tried his ROM though.
CM10 has a thing called "2nd-boot" which allows us to boot custom kernels, from an already running kernel.
2.6.32.9 is the Linux kernel version (which btw, the number doesn't have anyhing to do with the Android version, but newer Android versions work better with newer kernels, that's why there is a WIP 3.0.8 kernel for the Defy). "Jellybean" is just the branch of code. That kernel has the ramdisk and init binaries (I think, kernel experts please correct me) necessary to boot JB.
Motorola has never actually released a kernel newer than that for the MS2, the "official GB kernel" it's an older kernel "built" for GB.
Hope it helps.
Thanks for answering!

[Q] Custom Recovery and Kernel's

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.

AOSP Kernel Choices

Which kernels do ppl use for AOSP ROMS? I have obly come across Samsung kernels so far and if I make the jump to AOSP I wanted to make sure I had a selection to choose from!
I'm using and am satisfied with the Chronic Kernel c:

What's wrong with the stock kernel? Stock CM10.2 is very smooth and fast.
Using KT as I wanted to try UC and UV but it's not smoother or anywthing

true, cm kernel is pretty smooth, but with others you have a lot of option like more governor , io scheduler ,oc ,uv ecc
kt not smoother? rofl maybe wrong configuration

Custom Kernel for Stock 4.4

I am running rooted stock 4.4, what custom kernel would go great for overclocking.
oxydo is quite simple, of that doesnt work out for you try m kernel, or the other way around, both are great
imo best oc kernel is DerKernel aka TrinitySeven.
I have flashed Franco Kernel, is that not very good

Hi, TotalMusic....
It's very good actually. I've used franco in the past, but not of recent. However, with the release of KitKat, I've just flashed the recently released franco version, r76. All seems OK so far. Nice and smooth.
Franco's kernels are known for their smoothness and speed, as well as being good for battery life.
But they don't support overclocking.

[Q] CM11 Kernel situation

Are they still going the CAF route? Or is that ending since it mainly had to do with freezes (if I recall) in 4.3?
It's going to affect my decision to go back to 10.1. I really want to have touch2wake on my kernel and these fixes to make faux and franco kernels function are starting to cause issues on 10.2.
AFAIK, these developers will not be supporting CAF =/

freezes on 4.3 was due to bug in aosp jss code, witch have been fixed in 4.3.1. so update to lastest cm.
and in 4.4 they will continue.
Yeah, I'm running the stable release of 10.2 with ziddley's franco kernel and it's causing issues here and there now. I was hoping they were going to revert back to AOSP. I guess I'll revert back to 10.1 to maintain my desired functionality for now.

Yeah, unless there's some way to get touch2wake working on 10.2; I heard you have gamma settings now with the caf kernel included so I figure I can maintain my color scheme.

try with other kernels.
On CM11 and Cm10.2 try these: 1) Modified franco and faux to work on Cm : http://forum.xda-developers.com/showthread.php?t=2487246
2) AK has CM exclusive kernel : http://forum.xda-developers.com/showthread.php?t=2473454

You can always follow a tutorial to build your own cm from source code and enable module support. In that way you won't be using custom kernels, everything will be cm 100%.
I am using touchcontrol in that way, and I'm quite happy with the results.

CM11 is great with hells-core. Touch control works, and battery/performance is amazing.
