This Kernel is DISCONTINUED and is NO LONGER SUPPORTED!
**I Do not own the device**
AND
**Overclocking can harm your device!**
READ THIS FIRST-
Code:
I am not responsible for bricked devices, dead SD cards,
thermonuclear war, or you getting fired because the alarm app failed.
YOU are choosing to make these modifications,
and if you point the finger at me for messing up your device, I will laugh at you.
Don't complain if your device explodes in your hand or vanishes into thin air..
Reporting bugs without logcat is the leading cause of male impotency xD

2] More Bluetooth Fixes (CM)
3] Added Sweep to Wake feature (maxwen) (Only for CM ROMs for now)
4] Added BT LPM driver.
5] Stability Fixes for CM9/CM10
1) I got sudden reboot , Force Close!
Recreate the problem and post a logcat or proc/last_kmesg
2) I have issues of Signal drop
Its not related to the kernel
3) Overclock:
Anything above 1.5Ghz can be dangerous and unstable, however people have reported stable 1.7-1.8Ghz config.
Nothing above 1.5Ghz is reccomended.
4) Best Governer for battery: Conservative Best Governer for Battery + Good performance: Lionheart Best Governer for JUICE aka Performance - Smartass2
I will not add any more governers and bloat the Kernel.
5) If you have any issues give me a logcat
6)DO NOT USE ANY init.d scripts!!!!!!
7) Can you please add X or Y feature? Depends upon what it is and how is it useful.
8) Battery issues? Make sure no app is constantly waking up the phone and preventing the phone from going into deep sleep.
Also thanks to than33 , hlavik, and stubbakat for experimentation on their phones!
Having a good recovery makes the process of modifying, tweaking, maintaining, … more
