| |
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.
