Try without the "v" on your tar command (tar df /dev/nqft0): I found on a
previous system (486-66 with an old hercules TTL card) that "v" on the tar
command what slowing down the system too much since it was writting one
line per file on the screen: then the tape had to stop (I guess the system
was not able to feed the tape fast enough), rewind a little bit and start
again, make an entry in /var/adm/messages, this was slowing the system even
more, creating an other error that was written again to the
/var/adm/messages, slowing down the system again..... You get the picture!

If I removed the v from the tar command, things were much better.

I since then replace the motherboard (P133) and the video card (SVGA), and
thins are smooth!

But, this may not be the problem....
