Best kernel? - Nexus S Q&A, Help & Troubleshooting

I need a new kernel because I believe Matr1x causes occasional reboots to my phone so what are you guys opinion on the best rom?

bedalus created a great thread/spreadsheet for us exploring that question https://market.android.com/details?id=ccc71.bmw
i personally use the trinity kernel.

I don't get random reboots unless I'm overclocking with 1460, then it resets the over clock to normal. However when I boot my phone it doesn't always work so I usually have to take out my battery and boot again. But I've had that problem since the last ROM I used (codename 1.20 a.k.a Neapolitan flavors ICS)
Nexus S - CyberGR Hybrid ICS (5), Matrix Kernel (15)

Up voltages by 25mv and that will fix your reboot problem.

Hey guys I'm using on my Nexus S(i9023) - CyberGR Hybrid ICS (5), Matrix Kernel (15),
min freq 200mhz, max freq 800mhz, I/o scheduler deadline, governor lulzactive , deep idle on, and I've the same issues of 309041291a, I flash this rom whit clean install , and I've random reboots 1or 2 a days, and however when I boot my phone it doesn't always work so I usually have to take out my battery and boot again. And when work hard with nexus I've a battery drain? Somethings wrong in my settings?

Air Kernel

sounds like you need to try a different rom or kernel

SebastianFM or Faux123 kernal?!

Well I'm a little confused with these kernels, I have tried using both kernels with ARHD and the only one that seems to work correctly is the SebastianFM. The fuax123 kernel just keeps my phones CPU cores both at 1.51ghz, without any intelidemand governors, also, regarding RAM management, which one is the best between the two?
If anyone understands why the fuax123 kernel is acting weird, please clarify cause I'm stumpted,
Thanks a lot!
They are both great kernels I used bricked kernel myself but used to use Sebastian kernel for a long time just try them both for a week see what you like the best

faux shouldn't be forcing both cores online, especially with his newer intellidemand tweaks. You can read his explanation on his thread. Which version of faux are you using? There was also a problem reported by some ARHD users that faux came with ondemand by default when they flashed the ROM. Reflashing the kernel should correct that.
I've used both kernels and both are fine for me, although different phones seem to prefer different kernels. It also depends on your usage pattern. As mike1986. himself says, if you're happy with your kernel, then don't change it.

Im actually having that very same problem of my governor being on "ondemand", how shall I reinstall the kernal, do I download faux's kernal from his forum or reinstalls ARHD and install the kernel given their during the installation process.
Thanks!

You can download the kernel from faux thread...and can flash it just like flashing Rom/any mod.....flashing kernel via Rom will give you the same results again....
Also if you just want to change the govener you can install system tuner to change it to intellidemand governer and apply the changes in system tuner to keep it for every reboot

Thanks for your fast reply!
I'll reinstall that kernal,
I don't want to install system tuner and need to have it always running in the background for the cpu to be in intellidemand, that's why I want the kernel to do it automatically,
but ill try and flash the kernal again,
thank you!
try bricked kernel
Sent from my HTC Sensation Z710e using XDA
Bricked Rocks , u should give it a try show-p kernel wid new badass governer
I tryed each kernel, and i had a problem with the first flashing of each one, dunno why!
i had to reflash always twice time, and at the second time everything were good.
i'm now holding Faux kernel, i think is awsome, let have a look at my attachments to see my battery usage with intellidemand..
bricked one is good too, as all the other users told u...TRY'EM ALL!

I have used Sebastian kernel for weeks. Tried also faux. I had my best experience with bricked on ARHD 6.6.3.

Best for sense 3.6 is Faux kernel
Well I've now tried Faux123 for a few days and my battery life has been drained, right now, at day 3 of having faux, I'm at 46% battery with 9 hours and 33 minutes of usage, though with SebastianFM I got like one and a half days, solid, If I was bothered I'd upload a picture showing my phone lasting for 1 day and a few hours with Sebastian. Dunno why but battery life/smooth phone really contradicts itself :/
What's a bricked kernel? I've always been hearing about it but don't entirely understand what it is, sorry but I'm kind of new to this whole kernel thing

Phone Reboot

why when I bring the frequency over 1000mhz the phone restarts?
i'm using CyberGR v14 and Air Kernel

You need to read about overclocking and all it entails, before raising the frequency mindlessly over the limit...

[Q] No frills CPU with stock kernel?

Can i use No frills CPU or any other cpu controller with stock rom and kernel?
Yes I believe you can as long as your rooted.
Sent from my HTC Sensation 4G
Yes, you can. However you won't be able to overclock anything since the stock kernel doesn't support that. You can only change governors and I/O scedulers. If you want to stay on the stock kernel but have the ability to overclock/undervolt, you can try SebastianFM's kernels.
I also tried to overclock my CPU with stock kernel. Is does not work and changing the governors just makes the phone a bit slower for me cause the kernel doesn't really support is. Try senseomaniac rom, has the bricked kernel. I am using now and works great.

You don't have to change ROM to use another kernel . If changing the governors makes your phone slower, you probably tried 'conservative' or 'powersave'.
Yeah I know for only changing kernel, but is much easier to flask complete rom then only kernel, kernels differ and are many for different phone roms made for spicific phone then kernel will work. I had screen off governor set to 1cpu and 192 fq, made the unlock slow

No i was unable to use No frills, i set min to 192Mhz, in the application it says 192Mhz but actually it stays at 384Mhz.
I think he meant stock rom. You need a custom kernel to change the frequencies and voltage, that includes lowering the lowest possible frequency (384 to 192).
Yes, i apologise, min was 384. Didnt pay much attention to the numbers

question about kernel governor

okay, so i flashed a kernel recently and it came with the smartassV2 governor. when i set it to this i notice that it jumps frequencies, and stays doing this. is this normal with this governor? and if it isn't how can i fix it?
PS: I'm running trickdroid v6.20 [TMOBILE]
with fusion ultimate kernel v1.0

Many people have this issue, if you have overclocked/ changed governor from stock change it back as it known to increase the problem.

You can change your clock speed under EOS setting.. I do not have issue with the ROM as I use the kernel which comes with eos ROM n don't flash other kernel.. Also once in a while when u update your ROM do a clean install not just update, by dong this you will have a clean ROM

Jointhrealms is right best method I have found is when you do have the tablet OC is to set the max CPU 1 level lower then max and min set less the 1000
And best governors so far itellidemand on demand ,interactive sometimes Wheatley
Example harmony kernel
min 918 max 1528(can't remember exact #)
Governor itellidemand
I/o sched: Noop
Samsung Galaxy S3
AOKP 4.2.2 by Task650
Ktoonz Kernel w/KingBeatz
TF101 A.R.H.D ICS w/KingBeatz
The random reboot happen when the machine sleeping and never when using
I nerver do overclock
I tried other governor but still random reboot in sleep
Is there anyone use last eos rom and kat kernal have random reboot problem and have solusion?
Is the all problem is the kat kernal caused?
