Tried to repro the bug with 2 external DP panels at 2k@60 and one eDP panel at 2k@60, using the config file provided on DRM-TIP(5.0.0-rc5+). Still not seeing any under runs. I tried video playback on 2 displays for 4-5 hours and also the suspend resume scenario without any success. Any particular workload or sequence you can suggest, which might cause this issue in particular?</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>
