However, this leaves the pending pageflip still stuck indefinitely. Pretend to userspace that it does complete, and let us start afresh following the modeset. which should keep the system alive after the failure. Could you please try a kernel based on <a href="http://cgit.freedesktop.org/drm-intel/">http://cgit.freedesktop.org/drm-intel/</a> #drm-intel-nightly and check that the system does recover, and then see if we have some more information about the root cause?</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>
