Can you please test <a href="http://cgit.freedesktop.org/~pzanoni/linux/?h=edp-reverts">http://cgit.freedesktop.org/~pzanoni/linux/?h=edp-reverts</a> ? Please _make sure_ you're on the edp-reverts branch, and also please make sure you're using i915.edp_delays=4 and drm.debug=0xe as the Kernel command line parameter. After you boot, please also run dmesg | grep "eDP delays" just to make sure you're using the right option :) If this works for you, you can try reverting the top commits until it stops working. Thanks, Paulo</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> </ul> </body> </html>
