I'm attaching a screenshot of the last lines that appear on the screen before everything hangs. As far as I could reproduce, the last lines are always [drm:intel_power_well_disable [i915]] disabling DC off [drm:skl_enable_dc6 [i915]] Enabling DC6 [drm:gen9_set_dc_state [i915]] Setting DC state from 00 to 02</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are on the CC list for the bug.</li> <li>You are the QA Contact for the bug.</li> </ul> </body> </html>
