<pre>Im running current drm-next-4.15-wip Kernel and I use AMDGPU with Radeon HD
7970
DC disabled.
The following is wrong:
-Performance in Shadow of Mordor internal benchmark decreases from 68 to 61 fps
-also other games see a small decrease of 1-2 fps
-I see random screen corruptions on my desktop
-after I exit from a game, the system is unstable, screen corruptions are even
more visible and the systems randomly hangs
I bisected this to:
fd8bf087dffc0bce047c5aea2afcb8f821e48db1 is the first bad commit
commit fd8bf087dffc0bce047c5aea2afcb8f821e48db1

This is probably not making any sense, I guess one of the previous commits
related to BOs are faulty. To double checked things I used git checkout between
those commits and make clean during the steps. Its still very unusual but maybe
a dev know whats going on.
