Not running X on this machine. Just have the usual text consoles on
cntl-alt-F1 through F6.

Don't have a separate video card either.

When the machine stops I cannot access it by network. Even existing
connexions stop working. Being ext4 with full journalling, the file
system is safe.

If it's video drivers, maybe upgrading to beowulf will clear it out? Who
knows? It's probably time to do that anyway.

There is, I su[[ose, a slight chance that the specific installation of
ascii I had on the hard drive I moved from another machine isn't quite
compatible with the hardware I have now. But they're both AMd64
processors of comparable vintage.
