Title:
  Ubuntu 16.04 consistently freezes up / hangs

Status in linux package in Ubuntu:
  Incomplete

Bug description:
  Not sure what package this is related to. My best guess is Unity, but
  i honestly have no idea. After upgrading from stock Ubuntu 14.04 to
  16.04 on my Dell Inspiron laptop consistently freezes up and is
  unresponsive 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. So i wonder if this has something to do with my memory buffer
  or something. It seems to happen more often in Google Chrome than
  Firefox, but it happens with both. I know Google Chrome uses more
  memory though. And it has happened at least once with no videos
  loaded, so i doubt it's some sort of weird flash issue. 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.

  I will try to upload any log files that people think may be useful. I
  will see if i can do the recommended ssh monitoring method while
  trying to reproduce it to see if i can see an error that way.

  
  Not sure if this hardware info helps:
