The tape drive is on a x86.  Remote dump/restore works on the Sparc
works.  Pretty odd, but this might be good to know that it can read its
incorrectly written data?  I'll bet the sparc can't read a x86 dump...

Its when the x86 tries to read the sparc dump.

Got it.

I'll see what I can do about getting two dumps to you; as well as a test
on if the sparc can read a x86 dump.
