    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.
