R9285 Tonga it seems that on various agd5f DC kernels using mpv -fs --hwdec=vdpau <a 2160p60 very high bitrate video> screen is 1920x1080 DVI-D will sometimes produces logging with a few [drm:fill_plane_attributes [amdgpu]] *ERROR* Unable to reserve buffer grepping kernel log shows this is not new + only seems to happen with a DC kernel (I spend more time in non DC kernels and have no instances with those). First record April 3rd, but then it doesn't always happen and I don't always run that test so it could have started earlier. With just a few of the errors no bad effects noticed. Today, with current agd5f amd-staging-4.11 I got a display lock with logging below, I can't reproduce the lock, but can get a few of the messages to show.

Seems to have gone away with current amd-staging-4.11
