Something new in the dmesg output that may be helpful: [ 1.737127] WARNING: CPU: 0 PID: 66 at drivers/gpu/drm/i915/intel_display.c:1074 assert_pipe+0x82/0xe0 [i915]() [ 1.737129] pipe A assertion failure (expected on, current off) Please let me know what else I could do to help.</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> </ul> </body> </html>
