It still exists in drm-intel-nightly: b10dc96 drm-intel-nightly: 2015y-05m-05d-07h-49m-44s UTC integration manifest (I had to revert "drm/i915: Implement the intel_dp_autotest_edid function for DP EDID complaince tests", as it caused a compilation failure.) I tried raising the retry count in drm_dp_check_act_status(). With that the "[drm:drm_dp_check_act_status] failed to get ACT bit 1 after ..." message was gone and an extra log message stated that it worked after round about 66 retries, but the problem with the external monitor remains.</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>
