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>
