Public bug reported: Randomly the systems freezes for about 1 or 2 seconds, and the just reboots. I can hear the fans starting to go faster so I think the CPU must be running at a 100% the few seconds before reboot. I can not find any way of triggering this fault, it is just as likely to happen in almost idle as in heavy load. Below is logs from the the minutes before reboot. The reboot happened about 10:48:30
