--- Comment #2 from Michel Dänzer <michel at daenzer.net> ---
The messages appear when the AMD GPU is woken up due to userspace using some
functionality of the amdgpu kernel driver.

Does

 amdgpu.runpm=0

on the kernel command line prevent the stuttering? If so, I hope somebody can
help you track down how userspace is causing the AMD GPU to wake up.

(Note that the above will keep the AMD GPU powered on all the time; it's
intended to confirm that the stuttering is related to powering up the AMD GPU,
not as a permanent solution)
