Public bug reported:
While watching a YouTube video, screen went blank. Audio cut out, after
a few seconds the audio started playing normally for a few more seconds
then kept repeating the last half a second of audio for a few more
seconds. Then it stopped and nothing responded.
It did this a few times over the course of an hour. Had to power off the
PC to get a reboot. Last time it did this I ssh'd from another PC to get
dmesg and syslog info as it happened. Attaching those captures.
