Subject: Problem with SCSI DAT tape drive
Sender: questions-owner@FreeBSD.org

FreeBSD Team,

	I'm running FreeBSD 2.1.0-Development (Feb 10th snap) and just tried
to do a backup to a SCSI DAT tape drive. Any access to the drive causes
a kernel panic. The drive is a WangDAT drive

aha0 targ 4 lun 0: type 1(sequential) removable SCSI1
aha0 targ 4 lun 0: <WangDAT Model 2600      01.2 >
st0: density code 0x13, 512-byte blocks, write-enabled 

The panic is type 12 (page fault - page not present). The current process
is "Idle".

My other SCSI devices are working fine and the drive is known to work on other
systems.

	Thanks,
