Is this still issue? Seems very similar to 97264 (in my case, it's just happening much more frequently, maybe due to a greater count of pixels). If it's the same bug, yes, it's still present. I don't see this issue anymore on 4.8.15-200.fc24.x86_64 Lucky you ;) Still have the issue reported at 97264 on 4.10.0-041000rc3-generic With latest changes on atomic/WM work can you still reproduce on drm-tip? Hey, I have been playing with drm-tip for an hour: so far so good! :) Thanks, Cedric Cedric, any updates, good now? Yes, no blanking anymore ! :-) Didn't try any newer kernel since though. I guess that it's going to be merged in stock 4.12 ? Still get occasional lockups (mouse ultra slow to move/huge lag, everything else frozen), but I guess that it's not related to this bug. Thanks !

Thanks for your feedback. Then closing as fixed |

Created attachment 127796 [details] dmesg with debug output From time to time (once every 2 hours), during the work (key press??), display blacks for ~2seconds. After that, everything restores an is fine again. Once that happens, dmesg says: *ERROR* CPU pipe B FIFO underrun Dmesg with debug output is attached. Kernel: 4.8.4-200.fc24.x86_64 I tried to run intel-drm kernel but I was consistently getting "double free" error during boot-up.
