So I've been rooted and running Lego ROM for a little over a week now, and I've had no problems with it overclocked or anything. But recently, I've been down visiting my nieces, and so enabled the lock screen. Now, whenever I try to unlock with my pattern, the CPU usage shoots up (I've got a cpu monitor running in the tray) and it crashes, then reboots. On reboot, it doesn't really work, so I've got to remove the battery and do a real startup.
