I was slightly surprised to see the word "Broxton" since Intel canceled that product line before it was ever released. However that just seems to be an incorrect label arising from multiple Intel product lines sharing chipsets... The system is really a J3455 (Apollo Lake) and shares some silicon with the Broxton line.
Still, since you have a very new system you might find success in using a newer kernel. So try installing package 'linux-image-generic-hwe-16.04-edge'. If that does not solve the problem then please try the very latest from here: http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.12.8/
