I don't have any other tweaks applied except freezing a few programs on the safe list. I did have the program "lock supress" to turn of the screen slider, and since I stopped using it I'm going on 24 hours without a random reboot.
Kinda bummed--if that was the problem. I loved the ability in 2.1 to disable the slider lock, and had kept it up through .15 by doing incremental upgrades.
Anyone else know of a way to disable the lock screen? No lock is ok, but any button unlocks the screen, and I like the home/power button only option.
