<pre>Can you try a newer kernel? I'm afraid some fixes which might be relevant for
the "Pageflip completion event has impossible msc" messages have only landed in
4.9-rc though.
I'm not sure the issues with the second monitor are directly related to those
messages though. Might be related to this instead:
[ 256.507250] [drm:radeon_dp_link_train [radeon]] *ERROR* channel eq failed: 5

[ 256.507269] [drm:radeon_dp_link_train [radeon]] *ERROR* channel eq failed
