Comment 48 for bug 1680904

There are two patches to address the issue, one for v4.11[1] which can be backported for 4.10 for zesty and current 4.11/master-next branch for artful. The other one has been landed in v4.12[2].

I assume the first patch[1] should be landed for zesty. I can not reproduce the issue on Lenovo Thinkpad X260 with the fix, anyone has the issue can download the prebuilt deb[3] for a test.
