As background, this is the system from which I run my amanda backups for
my network, and for the last While I've been unable to get a 2G partition
to make it to my tape drive. I just get "I/O error" from the amanda tape
process, no messages on the console indicating problems.
Anyway, I was just doing a tar backup from a filesystem to tape.
I used "tar cbf 200 /dev/rst1 ." and a fresh tape (and I've just used the
cleaning cartridge, too).
Several minutes into the backup, the system locked solid, and appeared to
do some SCSI bus resets.
I could not change from X to a text console, I couldn't get any response
from windows already open on another machine. The X cursor was frozen.
I could not invoke the kernel debugger.
The corner of the xconsole window showed:
sd0(ahc0:0:0): SCB 0x8 - tim
SEQADDR = 0x94 SCSISEQ = 0x1
Ordered Tag Queued
and that was it.
I've got an Adaptec AHA 2940 (BIOS v1.23), and here's a hunk of the boot
dmesg. Any suggestions?
