Once again, I don't have anything connected to DP, but the following is logged: [ 510.536908] [drm:intel_dp_aux_ch [i915]] dp_aux_ch timeout status 0x7143003f [ 510.539555] [drm:intel_dp_aux_ch [i915]] dp_aux_ch timeout status 0x7143003f [ 510.542180] [drm:intel_dp_aux_ch [i915]] dp_aux_ch timeout status 0x7143003f [ 510.542194] [drm:drm_dp_dpcd_access] Too many retries, giving up. First error: -110 Do you have any test case to trigger it faster?</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are on the CC list for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
