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 tries [ 256.507269] [drm:radeon_dp_link_train [radeon]] *ERROR* channel eq failed [ 256.646139] [drm:radeon_dp_link_train [radeon]] *ERROR* channel eq failed: 5 tries [ 256.646156] [drm:radeon_dp_link_train [radeon]] *ERROR* channel eq failed -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
