The problem is that some SCSI devices respond on all LUNs when they
should only respond on one.  Some other devices also lock up when
they are polled on anything but LUN 0.  Linux has a list of these
bad devices in drivers/scsi/scsi.c.  The list is called blacklist[].
All you need to do is write down the identifying info that Linux
is showing on the screen for the device (should be three strings
with the manafacturer, model, and revision).  Then add that to the
blacklist[] in scsi.c and recompile your kernel.  You should send
the info to someone on the linux scsi development team (perhaps
Eric Youngdale - ericy@cais.com) so that it gets included in future
Linux releases.

That should do it!
