I'm not familiar with how the K class is wired.  However, the ncr53c8xx
driver that underlies the zalon720 is extremely ratty.  On my C360, I
can precipitate exactly this panic just by inserting the zalon7xx module
with an unterminated bluefish card.

Although we really need to track this down and fix it (which I'll look
into doing), all it would do would be to detach the driver correctly at
that point (so you still wouldn't see any devices).  Could you look at
your SCSI setup to see if the driver has a point (i.e. is there a
termination or cabling problem)?
