Something of interest from another forum:
Rubix Focused 1.6
Rubix Focused 1.6
I think I may have found the issue....
Those of you getting random reboots. How many of you use SetCPU? All my users that are getting the reboots now are using SetCPU, and all have the "clock down when the screen turns off" profile setting.
I'm wondering if it's related to that. In all cases, my "reboots" have been right as I go to turn the screen off. I always associated it with what I was just doing...but maybe it's the SetCPU clocking the CPU down. The guy who reported the reboot today was on a call and said he looked at the screen after the call ended. It came back up and then just shut off.
