I can upload the whole dmesg if you want, but I assume this is the relevant part, ending with the final message (the previous message was half an hour ago when bamfdaemon died, which it does occasionally): Feb 14 16:51:03 yes kernel: [ 3435.777321] [drm] GPU HANG: ecode 6:0:0xbde7ffff, in compiz [3786], reason: Hang on render ring, action: reset Feb 14 16:51:03 yes kernel: [ 3435.777323] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace. -- ...how to report GPU hangs... -- Feb 14 16:51:03 yes kernel: [ 3435.777324] [drm] GPU crash dump saved to /sys/class/drm/card0/error Feb 14 16:51:03 yes kernel: [ 3435.777375] drm/i915: Resetting chip after gpu hang Feb 14 16:51:06 yes kernel: [ 3438.780562] asynchronous wait on fence i915:[global]:3b94e timed out Feb 14 16:51:11 yes kernel: [ 3443.772358] drm/i915: Resetting chip after gpu hang Feb 14 16:51:23 yes kernel: [ 3455.931636] [drm:drm_atomic_helper_swap_state [drm_kms_helper]] *ERROR* [CRTC:31:pipe A] hw_done timed out Feb 14 16:51:24 yes kernel: [ 3456.955546] asynchronous wait on fence i915:[global]:3b954 timed out Feb 14 16:51:34 yes kernel: [ 3466.171061] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [CRTC:31:pipe A] hw_done timed out Feb 14 16:51:35 yes kernel: [ 3467.195005] [drm:drm_atomic_helper_wait_for_dependencies [drm_kms_helper]] *ERROR* [CRTC:31:pipe A] hw_done timed out Unfortunately no GPU dump, due to the aforementioned lack of response to even an alt-SysRq-B, let alone ctrl-alt-F1.</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> <li>You are on the CC list for the bug.</li> </ul> </body> </html>
