Yea, I updated yesterday after seeing this and did manage to lock next-queued. Possibly not anything recent, though, as it seems whether I lock or not now depends on how I test - 1080i30 (+deint) with some 1080p60 on 60Hz display = lock. I had been testing before with 1080p24 or 1080i25 and retried like this today - it's still running after 9 Hours. Given the above the next commit I will try reverting in addition to aggressive downclock = 6ad790c0f5ac55fd13f322c23519f0d6f0721864 drm/i915: Boost GPU frequency if we detect outstanding pageflips and I will run samples where frame/field rate = refresh.</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>
