[Galaxy Note Pro 12.2 Android Development] superchurn:
There are a few people in this thread who've mentioned seemingly random reboots. I get them occasionally, too. I don't run Plex or Firefox, but I do have multiple users. I haven't noticed any reboots while charging.

I've tried flashing up-to-date firmware with full wipe and it hasn't solved the problem. I have baseband version P905XXUABOF4 and kernel version 3.4.0-g21b6e3e.

Logcat output shows a fatal exception before each reboot:

Probably unrelated: the lock screen doesn't unlock in under the second user when in portrait mode - the screen just turns off. Otherwise, the ROM is smooth and responsive.
