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. clickwir@mach:~$ uname -a Linux mach 4.13.0-25-generic #29-Ubuntu SMP Mon Jan 8 21:14:41 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux clickwir@mach:~$ lsb_release -a No LSB modules are available.
