This really shouldn't be happening, but I have heard of some of these
lockups with both disk drives and tape drives, scanners on the same
scsi buss but never heard of any solutions.
The first thing I thought of is that you ran out of tape, but that
shouldn't lock your machine.
Since it is rare this will be hard to trouble shoot, but how about
trying to test with something like dump or tar from an xterm using
strace to see what is doing when it locks up.
I have a similiar dat and have never had that problem and I have
two disks and the dat on the same scsi buss.
