--- Comment #100 from John Frei <johann_frei at yahoo.de> ---
Unfortunately the new ucode (hawaii_k_smc.bin) file doesn't work for me.

I don't know if it does matter but as I tried to install a Hackintosh system
recently I expericenced EXACTLY the same symptom(black screen, unresponsive
system) after a couple of minutes.

One could argue that it's a complete different setup but it is the fact that if
I disable the GraphicsEnabler then the black screen issue vanishes.
So maybe one can assume that the dpm (via hardware) is corrupt.

Is it possible to try (experimentally) the new amdgpu-pro driver for r9 390 on
Ubuntu 16.04?
Or can we expect to receive the same issue as the all-open stack, either way?
