Hello Thomas,

> Does it crash right away or just when doing something particular?
It crashed at 2100, this is when I run a few I/O intensive processes:
- backup (dump ext4 filesystem -> to a separate raid device)
- backup (dump ext4 on remote host -> to separate raid device)
- backup (dump xfs on remote host -> to separate raid device)

This looks like it is what caused it to crash.

The host was online and I went away for awhile, when I came back the system
had rebooted on its own (as I lost all of my X windows/etc).
