    SubjectiTCO_wdt stops CPU fan control
    Hi

    After many hours to testing, we found that the Hardware Watchdog Timer
    module causes our motherboard's BIOS CPU fan control to stop
    controlling the fan. On Linux bootup, the fan speed stays constant all
    the time.

    Setup:
    - kernel 2.6.20.1 and 2.6.21.5
    - iTCO_wdt loaded with ICH4 chip on motherboard

    If watchdog module is excluded from the kernel build, fan control
    works as normal.

    Regards
    Keith
