--- Comment #4 from Sergey Kochneff s.kochneff@gmail.com --- On ASUS Strix RX 470, “fan stop” works fine on firmware boot and in GRUB, but after loading amdgpu module fan starts to spin and never stops. Although it’s possible to emulate proper behavior with custom script/utility reading and writing sysfs files it looks like bug to me.
