Radeon R5 M330 gpu hungs when dpm enabled and running gpu intensive programs
with DRI_PRIME=1. If amdgpu.dpm disabled no freezes happens, but gpu always on
same clock speed. This happens on every linux ditro I tried. Oldest kernel I
tryed was 4.9, now I'm using amd-staging-drm-next kernel and still have
problem.

Also this happens with radeon module with radeon.dpm=1 but just before hung lot
of texture/shader artifacts appears on screen
