@meira Sorry, somehow I had missed Dirk's comment. According to that, 3.16.0-33 should be fixed. In which case, you can try the latest mainstream kernel. The rest of the comment #71 might apply:
If you can still reproduce it after that, then note from dri-devel list: "If you can reproduce this somehow, please boot with drm.debug=0xe and attach the complete dmesg up to the WARNING. We seem to loose track of pageflips under obscure circumstances sometimes. We have more band-aids queued up, but fixing the underlying issue would be better ofc." - http://permalink.gmane.org/gmane.comp.video.dri.devel/112025 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1384342 Title: kernel messages intel_crtc_wait_for_pending_flips correlate to compiz hang To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1384342/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
