@Rand: I had this with virtualbox or vmwareplayer running (do not remember which because I use both) and a vm was booting. Disabling some kernel flag related to watchdog helped and later using updated versions of virtualbox and vmware solved. The issue anyway.
There is a feature in the kernel (I think it is called watchdog or so) that tries to identify hangups and then triggers a reboot which is a good behavior for servers at least. However in my case it was a "false positive" because disabling the feature in grub did not bring any lockup but no more auto-reboots.
