It sounds like there may be a couple of things going on. First, your
scanner may not be returning sense information properly.
Second, the NCR driver may be doing something wrong.
It would be helpful if you could hook this up to your 7890 controller and
see what happens. In general, the Adaptec driver behaves a little better
than the NCR driver.
