My idea was that this happens because it sometimes waits for vblank when vblank interrupts aren't turned on yet. However after some source code investigation it turned out that it at least tries to turn on the interrupts before intel_display_suspend/resume is called. This seems to be not reproducible even in CI at the moment, so my guess was that something has been fixed already or the chances of reproducing it got even more slim.</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> </ul> </body> </html>
