What do you mean by "runs normally"? According to the error messages above, the pwm controls are stuck to 0, so they won't actually control anything. Thus I suspect that pwmconfig then doesn't find any correlation. You changed the script to ignore the error, but I fail to see what good it is doing, as the root problem is still there. I am curious why the w83627ehf driver fails to set the pwm values. I have such a chip here and I've been testing pwmconfig on it and it works just fine. What kernel version is this? Can you please provide the output of: (cd /sys/class/hwmon/hwmon1/device && grep . pwm*) -- Jean Delvare
