Hi all,

Found when testing the tip of drm-next on my A12-9800 Carrizo.

[root@carrizo linux]# git bisect good

When I load amdgpu I get a screen that is mostly white with red bars and then some noise. Nothing shows up in my dmesg log that is specific to this error.

When I load X it seems like it's working though. I do get noise when I resize mpv from full to windowed (and back) but it goes away.
