Changed some default settings (trying to find most stable configuration and reduce random reboots):

CPU:

- Intelliactive Governor [Interactive and Intellidemand also recommended].

- min freq - 300Mhz

CPU HOTPLUG:

- MPDecision - disabled

- Profile - balanced

- intelliplug - enabled

GPU:

- GPU gov - msm-adreno-tz

- Simple GPU algorythm - enabled

As someone stated - GPU frequency stays at max freq for all the time. It requires more investigation, but i don't have time in near future.

I/O Scheduler:

- Scheduler - FIOPS [both internal and external storage]

- Read-ahead value set at 512kB - both internal and external storage

Low Memory Killer:

- Aggressive [8MB, 16MB, 32MB, 64MB, 96MB, 128MB]

VM:

- Z-RAM size - 230MB [temporary value though... but it's working by default, and i think it wasn't working in previous builds;)]

Misc Controls:

- Power Suspend Mode - userspace
