[Cc'd to -scsi, subscription is on the way...]
bash# tar xfvR /dev/nrst0
tar: rec 0: read error on /dev/nrst0 : Input/output error
^C
[other xterm:]
bash# ps -xawl|grep tar

The tape drive is silent, all other targets on the bus can be
accessed without problems. I have positioned the tape with a script
thats doing
camcontrol cmd -u 0 -n sa -t 3000 -c "2b 4 0 v v v v 0 0 0" 0x$c3 0x$c2 0x$c1 0x$c0
(thats the LOCATE command if i remember right, it worked as expected)
could that have someting to do with it? Normally i would just reboot
but maybe there is something i can check to help isolate the problem?
System is 3.1-stable, checked out Apr 10 (cvs-cur.5224), DDB is in
the kernel and i can rebuild it with -g (or so i think. :)
Awaiting instructions...
