If I were you, I'd take a backup ASAP and double-check whether one
of your disks is dying. Perhaps there's some hint in /var/log/messages,

It might just be a lose cable.

Proceed carefully. If at all possible don't mount your disks read/write
until yon know more.

(Perhaps boot off an external medium, CDROM or USB stick).

I was on the system last night until close to midnight with no problems. There were only 3 lines for yesterday in /var/log/messages and one for just after midnight. libflashplayer seems to be segfaulting. Nothing then until 11:41:30 this morning, which seems to be when I rebooted.
