Hi. I have Mainboard* with F71889FG-based controller.

After f71882fg module loaded - it creates bunch of the sysfs entries,
and i can succesfully read temperature and fan speed values from it. But
i can't control the pwm with it.
I tried pwmconfig utility as well as writing to sysfs files directly.
sysfs values get changed, but actual fan speed does not.


Chances are the pwm outputs are not hooked up (yes manufacturers do that),
or that the fan you're trying to control is controlled by a different
pwm then pwm3 (yes vendors do that too).

Hans
