Thanks for testing. What do you mean with broken video? I tried going back in the email thread but I'm not 100% clear what you mean by this. BTW, drm-fixes-4.16 are fixes we intend to get into the 4.16 upstream kernel. amd-staging-drm-next is our development tree and quite a bit farther ahead in development. I'm trying to find fixes to backmerge to 4.16 to make everyone happy when it releases.
