/etc/rmt hangs

[Mark Litwack]

There is no way to get /etc/rmt out of the I/O wait
once it is stuck (or dump for that matter, if you
happen to be using it locally).

A patch is available from DEC to fix processes
that are hung waiting for I/O on SCSI tape drives.

The patch contains mscp_tape.o, scsi.o, and scsi_asc.o.

mscp_tape.o fixes the hang problem, scsi.o fixes a kernel
panic, and scsi_asc.o improves SCSI tape performance for
the DS5000.

Overall, a good set of patches to have.
