Comment 2 for bug 447768

Update: it just happened 3-4m after a clean boot. This time it happened "harder"... I could not even ssh into the box to try and inspect logs. Later inspection of the logs (after a re-boot) shows nothing in /var/log/messages or syslog or Xorg.0.log; they didn't get a chance to write before it really locked up.

Another interesting point. After a re-boot, I have no video at all, and if I ssh into the box, lspci doesn't even show a video card on the bus.

Probably unrelated, but maybe another clue: I have two drives in this box under mdadm, just mirroring eachother. After these hard crashes, they have to resync. It takes a while, and always works, but maybe it's a clue.

Seems like Something Bad is happening, perhaps hardware, but I don't know where to start, and don't want to just start spending money replacing components without a better educated guess. Any expertise? Thanks.
