Comment 4 for bug 1310064

I recently tried more than one monitor after changing DPM to battery and when the system went bonkers this time: it rebooted after switching from Xorg to terminal.

I readied a camera and snapped the attached photo of the last text. Here's a transcription for search result's sake:

I installed the package for mcelog but it probably doesn't matter anymore since the system rebooted.

Any ideas?
