There was a problem with snapshots that lead to incomplete checking
by background fsck which in turn could lead to the problem that you
were seeing (i.e., repeated failures until fsck was run manually).
This problem was fixed with version 1.54 of ufs/ffs/ffs_snapshot.c
which was checked in on Dec 14, 2002. Please verify that you are
running with this version. If you had this problem after that
conversion please contact me directly so I can try and work out
more of the details.

Subject: Panic with recent CURRENT (1 hour ago)
X-ASK-Info: Confirmed by User
Hi Kirk,
Panic message was: "Block already free". I had to fsck -y manually,
but nothing special was found and fixed. The machine rebooted over
and over and paniced always at the same place. This shouln't happen
I guess.
