out of curiosity - are you seeing that behavior using the modesetting or
intel-i915 xorg driver? my experience using modesetting (and glamor for
GL acceleration) has been pretty good on both skylake and kabylake
systems and has been more stable than the intel-i915 xorg driver. for
example i frequently watch youtube and other html5 videos with
suspend and resume has been working on my end for quite a while as well
- although there are certainly some *very* rough edges in this regard.
one sysctl knob that may help is:
