Hi Can you reliably reproduce this? If yes, how? I see you're using Kernel 3.13. Are you able to test a newer Kernel and confirm if the bug still happens? I see you're using Ubuntu. You could try to download a Kernel from its development version, or one of its many PPAs, or you could even try the drm-intel-nightly branch from http://cgit.freedesktop.org/drm-intel/log/?h=drm-intel-nightly directly. Thanks, Paulo
(In reply to Paulo Zanoni from comment #2) > Can you reliably reproduce this? No, it only happened once. I'll add a comment if it should happen again. Thanks, --Stephan
Feel free to reopen if you still face this issue with more recent kernel. In this case, please try to collect and attach updated logs and gpu error state.
