PSA: If you're experiencing weird fan behaviour on an ASUS motherboard after upgrading to Linux 5.17, blacklist the asus_wmi_sensors module

  Linux HWMON (lmsensors) sensors driver for various ASUS Ryzen and Threadripper motherboards

Linux 5.17 added the Linux ASUS WMI Sensors driver which provides sensor readouts for things like fan speed on some ASUS motherboards. However, some boards like the PRIME X470-PRO have buggy firmware where subsequent calls to the interface can make fans stuck at max speed or just stop spinning altogether, leading to unpleasant noise and forced shutdowns. The problem quickly shows up if you have something like bottom running in the background, constantly querying temperature sensors. A quick fix is to blacklist the module by putting the following in /etc/modprobe.d/disable-asus-wmi.conf:

• bottom
