  1. Machine Check Exception + Kernel panic


    I got kernel Panic with MCE 7 on my Athlon XP 2600 (kernel 2.4.18).
    I think it's a hardware problem, but not sure. The freeze arise
    from time to time, especially under heavy load
    (big cpu-mem transfert, kernel compiling, by example).

    What can be the problem ? Is this the better place to ask ?
    Thanks in advance. Details here under.

    On a 2.4.18 kernel (proc: Athlon XP 2600), I sometimes get this MCE:
    "kernel: CPU 0: Marchine Check Exception: 0000000000000007
    kernel: Bank 3: b400000000000833 at 3400000000000833
    kernel: Kernel panic: Unable to continue"

    Using parsecme I get this
    ../parsemce -b 3 -s b400000000000833 -a 3400000000000833 -e 7

    Status: (7) Machine Check in progress.
    Error IP valid
    Restart IP valid.
    parsebank(3): b400000000000833 @ 3400000000000833
    External tag parity error
    Address in addr register valid
    Error enabled in control register
    Error not corrected.
    Bus and interconnect error
    Participation: Local processor originated request
    Timeout: Request did not timeout
    Request: Generic error
    Transaction type : Instruction
    Memory/IO : Other

    Dont know exactly what it means. Hardware problem ?
    (bad RAM module, bad chipset, bad cpu?)

    The memory module in bank 3 is bad.

    .... bad RAM
