To fix that I think we should gracefully shut down all displays on reboot. I've posted a patch series to that end long ago. Someone could try to revive it and see if it helps with any of the remaining MST issues. I've pushed an outdated branch here: git://github.com/vsyrjala/linux.git panel_reboot_notifier_2</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>
