As a workaround, use upp instead as a workaround (write to the powerplay binary
directly). See: https://github.com/sibradzic/upp

I suggest using 5.4-rcX as AMD's wip kernels (amd-staging-drm-next and
drm-next) may still have a bug with pptable writing. Or you can try reverting

drm/amd/powerplay: do proper cleanups on hw_fini

Be aware that this method can cause issues with fan control, so you might also
need to manually set the fans after that. You can use fanctl to handle this:
