Status in linux package in Ubuntu:
Incomplete
Bug description:
After upgrading from stock Ubuntu 14.04 to 16.04 my laptop
consistently freezes up and is unresponsive to keyboard or mouse. The
only way is to do a hard shutdown. I'm usually in a browser when this
happens, and often watching a video or two. It seems to happen more
often in Google Chrome than Firefox, but it happens with both. It has
happened at least once with no videos loaded. I haven’t observed it
freeze / hang when I’m not in a browser, but that's mainly what i use
my laptop for, so that's where most of my time is spent.
