I was unable to get any hangs or display artifacts while doing 60 suspend resume cycles so it makes it impossible for me to debug. It would be optimal if you could enable (USB) serial console from kernel and set the drm module debug parameter to -1 before suspending and try to capture as much debug as possible. Then it would give an indication what could possibly be causing the lock-ups.</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>
