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
