I can confirm this bug on both Ubuntu 16.04 and 17.04 on Intel Kabylake
i7-7500U with Sunrise Point chipset. The 4.11 kernel you suggested
fixes the problem, so it is fixed upstream. We should try and backport
the fix into at least 16.04 and 17.04.
** Changed in: linux (Ubuntu)
Status: Incomplete => Confirmed
** Tags added: kernel-fixed-upstream xenial
