I see a similar problem on my system which seems very similar. I have a
dos partition on the scsi disk and whenever I try to access this, the machine
hangs for about 10 secs. and I get similar error messages. Everything works
fine as long as I don't try to access the dos partition.
Does anybody have any idea on how to fix this?
