    Subjectbluesmoke, machine check exception, reboot

    Hi there,

    I have a Dual PIII-1000 running 2.4.18, and am occasionally getting the
    following error:

    > CPU 1: Machine Check Exception: 000000000000000004
    > Bank 1: f200000000000115
    > Kernel panic: CPU context corrupt

    This results in a hard lock (unable to use magic SysRQ key to sync or
    reboot, etc). I located these errors in arch/i386/kernel/bluesmoke.c in
    the function intel_machine_check(). From what I have read on lkml it is
    probably a result of the processor overheating and causing errors.

    I intend to add another fan to stop this from happening, but in the
    meantime is there anything I can do to get the machine to reboot after the
    panic? After the last time that this happened, I set
    /proc/sys/kernel/panic to 10, but it hasn't happened since then so I can't
    tell whether it will work. The error listed above is the entire error
    before the machine fails - there is no register dump or anything after
    that.

    Do you think it will manage to reboot with a hopelessly confused
    processor?

    Thanks,

    Corin
