At 4 AM this morning (during cron run, I suppose) a box running 2.6.1
hit the oops below. It locked solid, had to hit the reset button to
reboot it. The machine had been running 2.6.1 for about a week prior
with no problems.
Hardware is single Pentium Pro 200, 128 MB RAM (extensively
memtest86'ed). Kernel is no-SMP, no-preempt, and (obviously) no-highmem.
Feel free to ask for more details if I can help. This is the first oops
I've seen since mid 2.5.x on this machine.

Yes, but it is old.

Bit 15 of %eax got flipped. The kernel indexed off it and oopsed.
This is most likely a hardware failure.

Yikes...I should have noticed that bit. You're certainly right. Guess I'm in
the market for some RAM. Sorry for the noise.
