Nevermind, it seems that i jumped the gun. It happened again. If i had
to guess i'd say that the freezes are more likely to occur when the
computer has been on for awhile and is in moderate use. Others have
hinted at processor heat problems, often when one freeze occurs and the
computer is immediately rebooted the freezes occur with more frequency
(perhaps because the processor is already hot?).

Title:
  Ubuntu 16.04 consistently freezes up / hangs

Status in linux package in Ubuntu:
  Confirmed

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.
