I'm using an R9 390 (PowerColor Radeon R9 390 PCS+) on Fedora 22.

If I try to use DPM with the kernel parameter dpm=1, I get a black
screen/freeze after the login on GDM.
So I tried to disable DPM, which worked for me to use the computer for basic
work, but the 3D performance is very poor (even slower than my good old HD
5770).
Everytime I want to change the power_profile to high, I get an instant black
screen/freeze, too.
Then I cannot do anything anymore (CTRL+ALT+F1/F2... does not work).

Is it a bug in the power management/reclocking code?!?
