Can not set fancontrol using absolute paths

Running into the hwmon ids changing every boot, trying to set fancontrol using absolute paths. /etc/fancontrol looks like this:

INTERVAL=10

But when I try to start fancontrol service I get:

Re: Can not set fancontrol using absolute paths

Figured it out, https://wiki.archlinux.org/index.php/fa … lute_paths is confusing as it leaves hwmon2/pwm2 in the what the config file should look like AFTER modification section, whereas that should all be replaced by the absolute path as well. Changing my config file to look like this works:

Re: Can not set fancontrol using absolute paths

I spoke too soon, when I reboot, on startup I get this error now:

Oct 19 13:06:28 gekko fancontrol[1640]: Enabling PWM on fans...
Oct 19 13:06:28 gekko fancontrol[1640]: /usr/sbin/fancontrol: line 497: /sys/devices/pci0000:00/0000:00:01.1/0000:01:00.0/hwmon/hwmon[[:print:]]*/pwm1: No such file or directory
Oct 19 13:06:28 gekko fancontrol[1640]: Error enabling PWM on ///sys/devices/pci0000:00/0000:00:01.1/0000:01:00.0/hwmon/hwmon[[:print:]]*/pwm1

But after the system is booted if I start fancontrol service manually it runs fine.

Re: Can not set fancontrol using absolute paths

I fixed the error by adding amdgpu to /etc/modules-load.d/modules.conf, (even though it was not in /etc/conf.d/lm_sensors), which makes the pwm1 device available.
