- you shouldn't use Ondemand governor, it causes full reboots on kernel level in the slab part. Instead use Interactive, set On boot in Performance menu. Its stable
- wifi driver is not stable in the kernel module bcmdhd, caused reboot when switching it off then later on. Instead use either wifi always on or off.
I couldn't find any other critical issue with the rom after two days of constant use. Sorry for the inconvenience. With these in mind the rom didn't produce any other reboots here.
