Can you please file a bug at freedesktop.org against the i915 drm? A few other things - Can you check whether upgrading the ddx to 2.17 fixes this? Also please attach your Xorg.log and full dmesg. - Please grab intel-gpu-tools.git from http://cgit.freedesktop.org/xorg/app/intel-gpu-tools/ and attach the output of tools/intel_reg_dumper to the bug report. - If you're using swap, can you check whether disabling it works around the issue? And please put me as the assignee of the bug. Thanks, Daniel -- Daniel Vetter Mail: daniel@ffwll.ch Mobile: +41 (0)79 365 57 48
