I was cvsupping the GNATS database (the *entire* GNATS database, that
is - I didn't already have a copy) when I got this panic:
kernel: type 12 trap, code=0

Unfortunately, I didn't take a dump as I though it was a duplicate of
a previous panic (which it wasn't), but here's some relevant info:
(kgdb) l *(ffs_balloc+0x4af)
0xc0223b2b is in ffs_balloc (../../ufs/ffs/ffs_balloc.c:178).
173 if (error)
174 return (error);
175 bp = getblk(vp, lbn, nsize, 0, 0);
176 bp->b_blkno = fsbtodb(fs, newb);
177 if (flags & B_CLRBUF)
178 vfs_bio_clrbuf(bp);
179 if (DOINGSOFTDEP(vp))
180 softdep_setup_allocdirect(ip, lbn, newb, 0,
181 nsize, 0, bp);
182 }
When the machine rebooted, fsck complained of an unexpected
softupdates inconsistency. It turned out the /usr/gnats directory had
empty blocks in it and had to be truncated - a sizeable portion of the
GNATS database ended up in /lost+found.
