Re: VXA-2 packet-loader issues and AMANDA [Fwd: hard luck with the new autoloader]

So, you think if I disconnected the CD-rom (as a test), this would resolve the problem ?
The CD-rom is seldom used accept for emergency boots.
Also, I just tried a kernel with the ncr53c8xx driver and ultra conservative settings (for example,
setting to asynchronous I/O) and it behaves better. This time when I load the tape, I do not
get the strange error message in my original posting. It actually completed a small amdump, but then
failed again on the larger amdump. So, an improvement, but no cigar ... yet.
Yes, this is a 50-pin narrow cable plugged to the cd-rom and the 80-pin wide cable plugged to the rest
of the devices. Come to think of it, the 50-pin is just out there; no termination. Hmmm... let's try
that next.

So the cabling is your problem: you should use maximum 2 of the 3 connectors on
a SCSI card, since it's supposed to be a single long chain without branches.
It's the same on mine (I have one with internal narrow and wide, and external
wide connectors).
