<pre>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.
