Hi!
With Terry's suggestion I turned ATA WC off this morning, and now, this
happened: A crash when I pressed play in XMMS (this seems to be the
first page fault you see, and then, with fsck in the background:
yet another panic (UFS2 related?):
The crashdump is a bit odd, since I don't know why it actually paniced
(see the very end of this mail).

The most interesting part is this:
(kgdb) list
1167 struct buf *bp;
1168
1169 if ((error = ufs_getlbns(cancelvp, rlbn, indirs, &num)) != 0)
1170 return (error);

1172 panic("indiracct: botched params");
1173 /*
1174 * We have to expand bread here since it will deadlock looking
1175 * up the block number for any blocks that are not in the cache.
1176 */
(kgdb) print lbn
$1 = -12
(kgdb) print indirs[num - 1 - level].in_lbn
$2 = -12
(kgdb) print blkno
$3 = -2139222244046405632
(kgdb) print num
$4 = 2
(kgdb) quit
so, neither is lbn != the indirs[...].in_lbn (both are -12), nor is
bklno == 0, nor is num < 2. And it still paniced? HUH?
Where's the error? :)
