vram bios

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?!?

Mesa 11.1 (<-- Problem also exists on Mesa 10.6)

I'm not sure if it is the same bug as Bug 91880.

Things I forgot to mention:
The card works like a charm on Windows.
Setting the power_profile to low/mid doesn't trigger the crash.

If the crash was triggered, I can't connect to the ssh daemon via an remote device.
