--- Comment #3 from Bernd Steinhauser <linux at bernd-steinhauser.de> --- I noticed that I updated my kernel from 4.6.3 to 4.6.4 on 12th of July, so I thought it could be related and had a little investigation. Then I stumbled across this log, which I think was the first time this happened. This is from journald: Jul 09 08:59:43 orionis kernel: Linux version 4.6.3-amdgpu (root at orionis) (gcc version 5.3.0 (GCC) ) #1 SMP PREEMPT Sat Jun 25 21:20:12 CEST 2016 [...] Jul 09 17:04:08 orionis kernel: [drm:amdgpu_crtc_page_flip] *ERROR* failed to get vblank before flip Jul 09 17:04:09 orionis kernel: [drm:amdgpu_crtc_page_flip] *ERROR* failed to get vblank before flip No idea why in this case I can find some messages in the journal and in the other cases not. Anyway, this means that the origin is not the update mesa-12.0.0-rc4 -> final and also not linux 4.6.3 -> 4.6.4. Also unlikely 4.6.2 -> 4.6.3, since (as you can see above) this was built approx. 2 weeks before and within that amount of time I would surely have experienced the problem. (Had it approx. 8 to 10 times during the last 2 weeks.) Another message I found in a different log is: Jul 24 00:45:17 orionis kernel: [drm:amdgpu_atombios_dp_link_train] *ERROR* displayport link status failed Jul 24 00:45:17 orionis kernel: [drm:amdgpu_atombios_dp_link_train] *ERROR* clock recovery failed Not sure if it is related. With regards to what package started to bring this up, I'm now almost out of ideas. The only thing left would be kwin/plasma 5. The Update from Plasma 5.6.95 to 5.7.0 was performed on the 5th of July. So, since kwin is what I use as a compositor (and Plasma 5 as a desktop), it might be able that this triggers a bug? -- You are receiving this mail because: You are the assignee for the bug. -------------- next part -------------- An HTML attachment was scrubbed...
