I was actually watching the unblock-request bug for that, but apparently
it doesn't get updated when the package migrates.

I'm in the updated kernel now, and I confirm the fix. gpu_busy_percent
is now 0 rather than 99, and the output of 'sensors' for amdgpu-pci-0d00
now reports a fan speed of 815 RPM (down from 1478), temperature
readings of 55, 56, and 68 degrees Celsius (down from 66, 72, and 78),
and a power reading of 40 W (down from 94).

I wasn't hearing/noticing meaningful levels of noise from the fan(s)
before, but it does sound just a bit quieter now - and of course less
power draw, less heat generation, and less energy consumption are all
good things.
