I experience the same issue on my Skylake i5 :-)

IIRC in my case it goes away once I install bumblebee. Apparently something to do with switching between internal Intel graphics and the dedicated Nvidia chip, and not at all related to your issue, except for the symptom.

It's comedic because after bootup I have about 90s until lockup, so I have to be lightening-fast to type the commands to install bumblebee. If I'm too slow: reset machine, try again.

FWIW, this is on a notebook, running Ubuntu 16.04.

Try adding it to a startup script.

Thanks for the suggestion.

I was unclear, this only happens after a fresh install, before I've installed Bumblebee and its dependencies. Once that is out of the way, I don't need to worry about it any more.
