--- Comment #35 from Joerg Esser <jackfritt@boh.de> ---
I had similar problems until I used 3.18.7.
I couldn´t even boot beyond radeon load. The whole kernel crashed and my
Monitor showed no usable signal. I had to blacklist and load it manually with
option radeon.dpm=0, after turning on my Monitor . With kernel 3.18.6 I could
use the radeon option radeon.aspm=0, but still had to turn on my Monitor before
radeon module load.

Now with this kernel I only need radeon.aspm=0 and no blacklist option, either
the Monitor is turned on before or after radeon module load. Also GPU speedup
with Video output works fine.

Thx alot!!

Here´s my card info
