I have exactly the same hardware:
[  +0.000006] Hardware name:                  /NUC6i5SYB, BIOS
SYSKLi35.86A.0044.2016.0512.1734 05/12/2016

I can reproduce the mini-hangs/complete system freezes as frans described on
kernels 4.3.3-303.fc23+. Issues are always reported in dmesg.

Kernel 4.3.3-300 gives me various i915 related stack traces, but with no impact
to usability. (no hangs/freezes)

The best method of reproducing mini hangs in kernels 4.3.3-303.fc23+ that I've
found so far is: Run Kodi (requires RPMfusion repos), then start Firefox. The
issues start appearing almost immediately.

I also confirm what Jani Nikula said: Setting "i915.i915_enable_rc6=0" has no
impact on the kernels pertaining to this issue. You can look into dmesg where
it will be clearly stated that this particular kernel parameter is unknown.
