In 2.0.31-pre9 (i'll go ahead and upgrade to -pre10), after several
days of uneventful uptime, the machine (K6/233, Asus HX board,
96MB EDO DRAM, 3 EIDE disks, 3c590 netcard) got the following oops
and had to be rebooted in hardware.

"On two occasions I have been asked [by members of Parliament!], `Pray,
Mr. Babbage, if you put into the machine wrong figures, will the right
answers come out?' I am not able rightly to apprehend the kind of
confusion of ideas that could provoke such a question."
-- Charles Babbage
