I used to get that same panic occassionally during reboot, in the part
where it ran fsck.  It would get through several fstab entries, telling me
that the partition was already clean, and then it would either hang (in
some sort of permanent tsleep) or give me the panic.  Fortunately, the
hang or panic came before any of the partitions ever got mounted, so I
never lost any data.

I also think I remember having it happen once during the nightly (daily)
job, but I'm not sure.
