    SON OF A GUN! My problem is apparently fixed!

    Here's what i did:

    1) took out my cpu, and removed all lables from it. This included
    the little paper inventory tracking tag, and the plastic warranty
    lable (it was already out of 30 day warrenty). DO NOT REMOVE THE

    2) Removed the cheezy rubberish heat transfer pad from the CPU

    3) I had some really good heat transfer grease, the nice gray,
    thick, gunky kind, and slathered (well put about enough for the
    size and thickness of a dime or small coin) it on th processor.

    4) Put everything back together. I will note that I put the cpu
    fan on before I pushed the ZIF socket lever back down. This was
    an accident, and probably didn't do anything.

    5) Reset my motherboard to 100Mhz memory, and full (350Mhz)

    My usual test has been multiple, concurrent long compiles, like
    the kernel and Window Maker. I would get consistant segfaults
    and/or ASM errors EVERY time.

    Now everything works normally. My guess is that the labels
    created small hot spots in critical areas of the CPU. The rest of
    the CPU would stay very cool, but just a few hot spots would
    exist. Probably the combination of the transfer grease and
    removing the labels eliminated the hot spots and everyting works
    very well. The interesting thing is that it would only happen
    under intense load, and ONLY under Linux. Guess you can be TOO
    efficient sometimes :)

    My faith in AMD, FIC, and Linux is restored. My faith in myself
    is a bit humbled, however :)
