I have a similar problem of "panic errors" when attempting to do tape
backups. Here's my set-up:
Dell Corp.'s System 300, 4 Meg Memory, ESDI Hard Disk with dual controller,
1.2 Meg Floppy with an Irwin internal 40 Meg mini cartridge on the second
floppy cable, uname -a of:
release=2.2.3 [only relevant lines]
version=SysV
machine=i80386
When I received this system, I installed a Consensys Corporation, 8 port
smart card and the device drivers. Attempted to do a tape backup (ie.
dump, backup, tar, (no cpio yet but...I don't think it will work) backups)
but got "panic errors" with a crash every time. I still can't do them in
multi-user mode. "What to do?":
At the end of each day I make sure everyone is logged off, and do a
"shutdown 0". Then go into "maintenance mode" and the tape backup
works fine. What I have surmised is:
The device driver gets loaded but not 100% activated until the
following line in the '/etc/rc' file gets activated.
/etc/powercheck -f 30 /dev/ttyh1 >/dev/console 2>/dev/console &
The powercheck program runs every 30 seconds. So, in multi-user
mode, I can get up to 30 seconds into my backup before getting the
"panic error". It got frustrating until I figured that one out. So,
what do I do? I was told by Consensys that it was SCO's problem
since Consensys used non standard interupts, etc. and SCO said that
it must be a problem with the Consensys drivers since...... :-{ :-{
You, know, the usual.
I have it working well enough to do satisfactory tape backups so I'm not
really complaining. It would be nice to get backups working in multi-user
mode just to save the time it takes to go back and forth between
multi/single-user modes. As stated above:

That was my 1/10 cents worth ;-)
