Please try the latest hwe stack by. I'm using kabylake + the hwe stack without issue at the moment.
sudo apt install --install-recommends linux-generic-hwe-16.04 xserver- xorg-hwe-16.04 More info is available here. https://wiki.ubuntu.com/Kernel/LTSEnablementStack I'm also closing the intel-microcode track of this bug as at the moment this does not appear to be hwe related.
