Bug#498019: kernel: random system crashes and restarts (about once every week)
Package: kernel
Severity: normal
from time to time I find that my system rebooted without me asking for it.
sometimes it happens while I'm using it, most often it simply reboots.
I have a look at the /var/log/messages and I find a few recurrent
problems:
