Still testing 4.7.0-994-generic. It again isn't freezing. Perhaps the
time it froze was not because of the main issue. Hard to say, very
confusing. If nothing else i believe it is more stable, but it still has
sporadic freezing problems of some sort.

I've heard reports of even macs having freezing problems in the latest
updates. Do macs and linux share open source kernel code and drivers?
Could it be the same problem, that some sort of Intel driver for i915
has just had a poorly written driver which is causing all kinds of
freezing problems among a range of systems?

I really wish this could have been fixed by now. Just frustrating. I
know code regressions happen, but freezing kernels are a bad one.

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.
