I haven't seen this specifically, but I have noticed a fair amount of
instability related to the snapshot code. I've managed to crash
5.2-RELEASE through 5.4-RELEASE by keeping too many snapshots, or
hammering the disk while taking a snapshot, or having a filesystem with
lots (close to a million) of files.
Have you tried fscking the disk manually from single-user mode?
