I was just wondering about the kernels for CM7, it seems like every other week pershoot comes out with a new kernel, what's the advantage of flashing the new kernels?

Battery life, performance and under the hood stuff mostly. Pershoot is UV'd really low so you'll get better battery life. It's smooth as butter too. Flippy's is just a monster.
So, we can flash a new kernel, when we already have a CM. I'm on CM7, can a flash a pershoot kernel still? Would I have to wipe data, and re-flash CM7, then the kernel?
Just dalvik and cache if anything. You'll be safe with Pershoot's kernel if you're running anything that came out after nightly #31. I'm not sure about the G2 Fast kernel but it might be the same way. That's when the new gpu drivers came out.
Ok, that sounds good, better battery life is always worth it.

Honestly i have found that Flippys kernel includes the powersave governor, using that with a screen off profile in set cpu is a HUGE battery saver, as long as when the screen is on your not clocked too high cause then it defeats the purpose.. .. not to mention it includes the ability to well.. go fast..
Hello all,
i have been an owner of a nexus s gsm s-lcd since August 2011 and i have been experimenting mostly with cyanogenmod and cyanogenmod based roms such as nscollab.
Using my phone mainly for my jobs, since the beginning of the usage of non official roms, i am always having stability problems ending up not trusting my phone for everyday use.
I have tried cyanogenmod stable, rc, lots of nightly builds and various nscollab versions from 1.0.39.
From my experience so far, except when using matr1x 5.5 cfs i always have some of the following problems, some times some of them and sometimes all of them:
1. reboots
2. reboots with no ability to load the os, with only solution the removal of battery
3. crashes with the result of the pin needed to be given again
4. never waking up after deep sleep
The kernels i have used so far are all the matr1x cfs(sorry, i do not trust con Kolivas and his bfs, being a linux user for 10 years), various netarchy and the stock cyanogenmod .
The only kernel that has been stable for me until now is matr1x 5.5 cfs.
The reason for not going back to the official rom, and be ok with my mobile is mainly the bln and voodoo(although i have bought the paid app and i can use the module with the official rom) modules.
The first thing I though having all these problems is that the main cause of them would be the undervolting that all most of the kernels have. After some tests i realized that with the voltages that proton suggests or even with the stock voltages, the problems do not disappear.
Although, i have found my stable kernel and i always flash matr1x 5.5 cfs in all the roms i use, i would really like to know what is the usual suspect of all these problems. Is there any possibility that some of them are not kernel related and the cause is in the source code of cyanogenmod?
To sum up, i really believe that we should try an effort to create a kernel that is very close to the stock one, and be very careful with the extra modules that we add. Although i do not have the experience of making a kernel package for android, i will try for sure to make a flashable kernel for my needs, and if it's stable i will upload it and share with all of you.
I believe that every mobile has to be bug-free(as possible), and reliable for everyday use and at least i should be reboot-free.
I would really like to read other users experience and opinions.
Regards,
Michael
it was the same for me. nscollab was unusable since it was always freezing in two minutes after boot. changing the kernel did not help. so I decided to change the rom to Nexus MV 10.05. it works very stable (not a single reboot or freeze) and faster than nscollab.

Well, I found that custom kernels can work with stock ROM's. I'm using stock Google 2.3.6 on my 9023 + pete's kernel with Voodoo sound and BLN. Stable as ****, practically no issues, I'm happy with my NS as never before just because of the lack of constant flashing the **** around to "optimize". It just works flawlessly.
Here's the link to the kernel : http://www.peteralfonso.com/2011/08/download-nexus-s-263514-kernel.html
Had the no wake issue with cm7 216 and nscol 1.4.5. On nscol 1.4.6 and no problems yet. If it happens again it would seem to be a cm7 issue. While annoying devs are constantly hunting down and correcting problems, just the way it is and doesn't bother me.

Just use nscollab .46 because that has stock voltages and you should be fine

The hole point for me is not using any other kernel but the stock one.. compile yourself a nexus s kernel (google it for how to) and be happy without any reboot, crash..
baterry? normally 1.5 days @ 1.0ghz..
You could do that as well

.45 with stock voltages caused the "pin asking" issue even with stock voltages(even with 5.5 cfs - maybe a cyanogen problem?), so that's why i am stuck at .42 with 5.5 cfs and did not even try .46.
Try .46 and lemme know

If you see, in the thread of nscollab, there are also problems with the phone dying etc, even with the new stable cyanogenmod + matr1x kernel.
I only do tests in my mobile during the weekend, because i use it all week for my job. So stuck with matr1x 5.5 until i see a really stable matr1x kernel coming after 8.

Thank you very much for posting this link. I did not know that kernel. I just found some time to flash nscollab .50 with this kernel and i only changed interactive governor with ondemand to be even closer to stock kernel.
I hope that it is as stable as it is for you.
After some hours with this new kernel, i am not sure about stability(although it seems stable) but nexus is running smoothier than ever.
I've used ondemand from the beginning I started using this kernel, then I tried interactive (default) just to try it out. Not really a difference, same stability/speed and I could get rid of NoFrillsCPU app setting the default governor at startup. So to wrap up, kernel runs beautiful from the start, no extra fiddling necessary.
I do not believe the issues described in the OP are kernel related. They persist in all custom kernels. I think it is from Dalvik VM crash but I have no proof.

As I read here I am not alone in the problems described, and after lots and lots of tests i am sure that this is a matr1x specific issue.
So, as i do not have permission to write in a development thread yet, I suggest the following:
1. if the developer of nscollab wants to continue with Matr1x kernels, makes a new release with the last well known stable kernel, which is Matr1x 5.5 until Matr1x developer finds out what is the problem with the new kernels.
2. Matr1x is replaced with another kernel, such as Peter Alfonso's kernel(running FINE for 24 hours. In the same period with Matr1x kernels i would have at least 2-3 problems- 5.5 cfs excluded).
EDIT:
I just got the first "dead phone" issue with alfonso kernel. I should be more patient about stability results of this kernel, or this issue is not kernel related.
After many days of testing with nscollab and different kernels, i am sure that the major problem of "dead phone" is not kernel related but a cyanogenmod issue.
The most stable kernel i tried was Peter Alfonso, but after 4 days of use the issue appeared.
As i need a really stable rom, before going back to stock, i am testing Oxygen 2.3.1, which i do not know yet if it's stable(i hope) but until now is the fastest and smoothest experience.
Id say if you want stability, stay on stock, extra features like BLN and Voodoo sound are added via kernel anyway.

Kalimocho found a kernel error and a missing vendor file in the CM kernel. It will be fixed in the next nightly. The hope is that this was the cause of the freezes/reboots/bootloops/dimscreen bootloops that people were seeing.

lol i keep looking but i dont find anything
ahhhh
i realy want to use faux kernel for my nexus 7, it has jellybean 4.1.2, rooted, busybox, cwm touch..
my problem is when i flash faux kernel 011 all its version ive tried, i can properly boot it but the problem is i cannot shut it down or reboot it using power button or system apps, it always stuck for about forever in shutting down "power off" message. Even i tried hard reset and going back to recovery mode then boot it up again it still stuck and cant shut it down properly. Actually i even try factory reset and stock rom then different roms if faux kernel will not have that problem, still no luck. Ive tried everything how to properly flash kernels and roms. The only faux kernel i managed to get working on my jb 4.1.2 is faux 012b6 to 012b8, but again problem rises when i play games like buggy beach or riptide gp is it crashes, sometimes forced app close and complete freeze and i needed to do "hard reset". If any one can help me know about trick or two about faux kernel using on nexus 7 with jb 4.1.2 please help me.. i realy like and needed faux kernel because like for gaming its super smooth and fine, ive tried trinity , M kernel+ and franco but this realy owns in performance value... please help i realy appreciate it soo much .. from a happy gamer thank you.
I've had trouble with that kernel too. Flash the reset kernel. Flash LeanKernel and be done with it.

Beta 0.5 also if you want to over clock flash the powerHAL binaries. Otherwise the max freq will reset.

thanks mate uber:fingers-crossed:... but i figured it out on nexus 7 jb 4.1.2 using "faux kernel 012b8" fastest ever kernel on the planet even when playing games run 65 fps smooth butter without crashing games like freezing and hanging to result in hard reset.. "stay at 300 min 1300 max cpu" and heres the trick using franco kernel updater " set cpu quiet governor to = runnable" . Thats it never had i experience crashing games like buggy beach, riptide gp or dark meadow ever again testing for about 3 hours non stop playing. Perfect kernel for those seeking maximum potential of your nexus 7 device when playing intensive games :good:. FAUX i love you mate for kernel 012b8:victory: btw im using AOKP jb n7 rom too, perfect combination:good:
