I have several Suns (4/280, 4/470, 3/60, 3/280) that are equiped with
Exbyte 8mm tape drives.  I am running SunOS 4.1.1 on all of them.
Whenever I attempt to do a restore using a remote tape drive the remote
system crashes.  The command I use is:

restore if tm:/dev/rst1

This command worked fine under SunOS 4.1.  The dump to a remote tape
command still works.

The only indication I get is in the messages file.  Below are the key lines.

Can anyone help me?  Thanks in advance.
