[Bug 1497627] Re: Periodically video will freeze for no reason at all and no specific time between freezes.


Today, at 15:54:11 the video froze on my system while opening a new tab
with Firefox 41.0. At the time of the freeze I was running kernel
3.19.0-28-generic #30~14.04.1-Ubuntu SMP Tue Sep 1 09:32:55 UTC 2015
x86_64 x86_64 x86_64 GNU/Linux and have since updated via an update to
kernel 3.19.0-30-generic #33~14.04.1-Ubuntu SMP Tue Sep 22 09:27:00 UTC
2015 x86_64 x86_64 x86_64 GNU/Linux. The cursor would still move but
nothing clicked on will open nor can I change to a different window.
This came after an uptime of 6d20h6m. I've attached today's syslog which
shows that until the time I rebooted after the freeze that background
operations were still working. The 2nd boot today was into the new
3.19-30 kernel.

Bug description:
  What I expect to happen is the video to not freeze every so often.
  What happened is that the video froze. This has been going on for over a year. It doesn't matter if I have any applications open such as Evolution or Firefox. It could happen any time during the day when I'm working on the computer or during the night when it's the most idle. Once the video freezes the cursor can still be moved around the desktop however clicking on anything does not work. During this time all background process and cronjobs continue to run.
