Ubuntu 16.04 flashplayer causing a hard system freeze

Asked by Wojtek K

I've been having an issue where my install of Ubuntu 16.04 LTS encounters hard system freezes when playing flash content. By hard system freezes I mean that the system locks up, replays the last second of sound and has to be restarted using the reset switch.

Some points:

I have not been able to get anything useful from the system logs when examining them after a crash.
The crashes are random. Sometimes they happen twice per day, while other times once per month.

I'm using Chrome () and have the Hardware Acceleration turned off.

My GPU is a 980Ti using NVIDIA binary driver - version 357.66 from nividia-375 (proprietary). I gone through a few different revisions (open source: 384.47, 370.28, 378.13, 381.22 and the Nouveau drivers) to no avail.

Chrome version is: Version 59.0.3071.115 (Official Build) (64-bit)

OS (lsb_release -a) :
Distributor ID: Ubuntu
Description: Ubuntu 16.04.2 LTS
Release: 16.04
Codename: xenial

I've also seen the freeze occur when watching flash content in a VM running Windows 7, which really surprised me.

Is anyone able to shed some light on this?

Thanks

Have you tried Firefox just to test?
Have you tested your RAM using Memtest86 from GRUB?

I've seen the same behavior when using Explorer in a VM.

No, I have not tested my RAM for a while now. It's a good point, but I don't suspect the RAM because I'm not seeing any problems with anything else. Usually when RAM is playing up you do get a lot more random issues popping up.

I will try to use Firefox for a bit, but I still suspect there is some other evil at play here.
