As mentioned in earlier messages, we're still trying to do a backup and
getting a crash every time. Our backup routine works by creating a command
file which is redirected into FTP. The command that fails is

put "|dump 0uf - /usr | gzip -9" usr.$starttime.gz

(where $starttime is the starting time of the backup; it's replaced with a
numerical UNIX date as the command file is created). 

As you can see, FTP is accepting input from dump, via gzip, and sending it
to the named file on the other machine. This is done over a separate LAN
segment for security.

The screen that flashes, just before the reboot, says that there was a GP
fault in the kernel. I can't print the screen or otherwise save it, and it
goes by very quickly -- faster than I can write down the information. (I've
considered grabbing a camera to take a picture.)

How can we nail this bug and get it fixed? We need to do backups, and
Heaven knows that if this userland stuff causes a crash, other things will
too.
