  I think I noticed a simliar problem once with the new SCSI driver.  I
seem to remember doing an init, which cleared it up.  The problem is very
likely due to the new SCSI driver negotiating sync transfer mode, and when
rebooting, the device is still sync while the kernel has defaulted to
async.  The 33C93 chip does not appear to have any way to do a SCSI bus
reset (a problem I remember from long ago in the amiga driver as well).  I
would guess that 33C93 designs would need to have additional logic to do a
SCSI bus reset.
