Yes.
It's an ordinary SCSI disk, attached to an NCR 53c875 type controller.

Hey!  Now that you say so: the internal memory bank is supposed
to be 8MB, it's obviously misdetected!  I never noticed that.
The size of the SmartMedia card is correct though, it's a 32MB card.

So this means the SCSI layer is suspect?

By the way: did you notice the message "unknown partition table"
in the log of 2.4.15pre1?  That message doesn't show up with a
kernel that works.  Now I seem to remember that there have been
a lot of changes in de gendisk functionality recently.
Those changes broke the detection of partitions.  This was fixed,
but could it be that these changes caused my problem?

I will try the other UHCI driver first.
Then I will upgrade to the latest pre-release of the kernel.

If all this doesn't work out maybe I'll try some ancient kernels
in order to find the patch that introduced the problem.
But that takes a lot of time, which is in short supply...
Does it make sense to try the latest ac-kernel first?
