That probably means this is a victim of commit f11cb1c19ad0 ("drm/i915/dp: revert back to max link rate and lane count on eDP"), which I think would have picked the lower link rate for us. Yes, eDP revision seems to be 1.4a: [ 1.385017] [drm:intel_dp_init_connector [i915]] eDP DPCD: 04 92 a5 so I believe that is indeed what would have happened.</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>
