came across this and thought I'd share it.
If you are using a PWM capable motherboard with the IT87 module and
you want to use fancontrol ...
If you can't load the it87 module - most likely your kernel needs
'acpi_enforce_resources=lax' as kernel argument. Add it to your boot loader for example.
modprobe it87save configuration, then run
lsmod | grep it87 --> make sure it's loaded
sensorsto make sure everything loads properly.
pwmconfig if pwmconfig gives you:
There are no pwm-capable sensor modules installed
You can get it working by loading the it87 module with the command:
modprobe it87 fix_pwm_polarity=1
pwmconfig should work as expected.
