I spent the last week troubleshooting it and therefor I want to share my current state. First of all it's not only with the X server. This bug appears on the same hardware when you try to load the i915 module with the option 'modeset' set to 1 (enabled). Also it is able to boot into the kernel as long as you keep the option set to 0. (Sadly you're not able to start an X server then) Further investigation (Thanks to the reporter) led me to analyze the workaround: (IMPORTANT FROM NOW ON ITS YET THEORETICAL ONLY, I am investigating further). Since the workaround in drivers/gpu/drm/i915/intel_dp.c forces the first block to never be executed, also nothing else changed, beside the addition of the if statement in line 2033 (I checked everything else). Therefor the bug is caused by the function (line 1882) 'intel_dp_dsc_compute_config', which returns true instead of false.</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> <li>You are the assignee for the bug.</li> </ul> </body> </html>
