    AFAICS the sequence of assembler instructions is impossible:
        eax: 9
        ebx 801fe8cc

    the faulting instruction is

    > 0: 8b 13 movl (%ebx),%edx <=====
        i.e. load an integer from (%ebx)

    and the CPU failed with:

    Unable to handle kernel NULL pointer dereference at virtual address 00000009

    but that's eax!

    I doubt that you are overclocking your computer, but could you check your
    power supply, cabling, cooling,...?

    And check your kernel log: oops always on CPU1, or on both cpus?
    What about these messages, is that common with eepro cards?
