Hello !
I reinstalled Manjaro one week ago, since then my graphics cards (AMD RX5700 XT) fans wont turn on unless I manually trigger them with Corectrl.
hwmon interfaces for GPU fan:
pwm1: pulse width modulation fan level (0-255)
pwm1_enable: pulse width modulation fan control method (0: no fan speed control, 1: manual fan speed control using pwm interface, 2: automatic fan speed control)
pwm1_min: pulse width modulation fan control minimum level (0)
pwm1_max: pulse width modulation fan control maximum level (255)
fan1_min: an minimum value Unit: revolution/min (RPM)
fan1_max: an maxmum value Unit: revolution/max (RPM)
fan1_input: fan speed in RPM
fan[1-*]_target: Desired fan speed Unit: revolution/min (RPM)
fan[1-*]_enable: Enable or disable the sensors.1: Enable 0: Disable
Just a hint. These errors: No irq handler for vector are causing by buggy bios. It is causing by PCI or PCIE and there comes the PCIE GPU and you see why it is not working ^^ Unfortunately It seems there is nothing that can be done, only suppress it, but if you feel adventurous, then have look at these kernel commands (and look for irq): https://www.kernel.org/doc/html/latest/admin-guide/kernel-parameters.html
