This latest incantation produces:
#root:orgy: {7} fmt.sh
Sep 16 22:03:05 orgy /kernel: (pass0:aha0:0:6:0): CCB 0xc04992e0 - timed
out
Sep 16 22:03:05 orgy /kernel: aha0: ahadone - Attempt to free non-active
ACCB 0xbf89d000
camcontrol: error sending command
CAM status is 0x14b
#root:orgy: {8} Sep 16 22:03:05 orgy /kernel: aha0: ahadone - Attempt to
free non-active ACCB 0xbf89d000

Usually the machine panics here (I think only when the id is 0). I've
been disconnecting the drive to allow it to finish, without the machine.
I'm using a AHA-1542B:
aha0: AHA-1540/1542 64 head BIOS FW Rev. 1.1 (ID=41) SCSI Host Adapter,
SCSI ID
7, 16 CCBs
I've changed the drive's id to 6. And it _still_ thinks it has 520 byte
sectors. :-/. Well, I've tried all that I can think of. I'm about to
return the drives to the owner and let him deal with it.
