We probably want to re-enable D3 after handling the HPD, so we'll follow up with a proper fix with that included. Could you still try the script in <a href="show_bug.cgi?id=99114#c2">comment 2</a> with the attached patches (w/o the change in <a href="show_bug.cgi?id=99114#c5">comment 5</a>) booting with drm.debug=0x8e? In case the problem goes away with these 3 patches then in addition the log with only 0001-drm-dp-add-DPCD-AUX-logging.patch applied would be interesting.</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>
