No, I think that the config file is innocent, which is why I want you to try to change the driver values directly. Please try the following sequence and report results: cat /sys/bus/i2c/devices/1-002d/fan_div1 echo 4 > /sys/bus/i2c/devices/1-002d/fan_div1 (wait 3 seconds) cat /sys/bus/i2c/devices/1-002d/fan_div1 (and try with other writable files in the /sys/bus/i2c/devices/1-002d/directory if you want, too) Thanks, -- Jean Delvare http://khali.linux-fr.org/
