photo of monitor with panic crash info
This happens about once a day. The machine is an older and slower unit
and normally very stable. It just does what it does, which is not much
other than giving me access to a serial port.

Not sure what other info I can provide. This was taken from a photo
of the monitor and done by hand where I think I managed to get it
all correct.
Happens every day more or less.
