Issue descriptionChrome OS Version: 52.0.27.43.116 (64-bit) Chrome OS Platform: Acer Chromebase 24 (2016) 8350.68.0 (Official Build) stable-channel buddy Network info: Ethernet Please specify Cr-* of the system to which this bug/feature applies (add the label below). Steps To Reproduce: (1) Attend video/audio Jitsi Meet room. (2) Wait ~5-10 minutes (3) Receive black screen, no audio, no video sending/receiving. Camera light will remain on entire time. Expected Result: ChromeOS either recovers and is usable, or doesn't crash at all. Actual Result: ChromeOS locks up (black screen) and does not recover. Occasionally we'll get audio streaming to work again, but video (sending) and video on-screen do not return. How frequently does this problem reproduce? (Always, sometimes, hard to reproduce?) Always/sometimes. Nearly every time using Jitsi Meet, this will happen while in a room with another user. Generally happens after ~10 minutes or less, occasionally takes an hour What is the impact to the user, and is there a workaround? If so, what is it? User must reboot / forcefully power off machine and restart. Please provide any additional information below. Attach a screen shot or log if possible. - Log attached is from /sys/class/drm/card0/error Initially reported https://bugs.freedesktop.org/show_bug.cgi?id=97543 as per message in a log. Of note, we experienced this in normal-user mode and moved to Developer to try to get logs for reasons why this is happening. Problem persists throughout.

I've been able to reproduce the locking up several times the past few days, but it never puts anything in chrome://crashes. I would assume this doesn't get wiped upon reboot? I have to forcefully reboot the unit to get back to a usable state before I can check the crashes area.

Just got it to crash again while having multiple video streams happening at the same time. Again, this is back on stable without being in developer mode. I went to chrome://crashes again and nothing was present. Attached is showing the screen in an off-state while having the power button on. Not really useful, but that's what it looks like when it locks up. As I was present this time, it did appear to continue displaying video (audio was muted so I'm not sure what was going on there) to a remote location. After a few minutes, it stopped displaying video alltogether.

There is a new stable out. Are you still seeing these problems paul.kasper@logicsupply.com?

I applied the update yesterday and have had a steady video stream since then. I had a graphical freakout at one point, but no crashes. I'll check with my remote user as well to verify that we can't reproduce.

No problems on the units we have any longer! The last OS update appears to have fixed the issue.
