This bug has already been reported in bugzilla:

https://bugzilla.kernel.org/show_bug.cgi?id=190281

Did you have any problems with older kernel versions? If so, would it be
possible for you to bisect?

Well, it happens on a laptop that I use quite intensively, so it will take 
some time to bisect. However, in the meantime I checked the old logs and the 
first recorded occurrence happened with 4.8.10 release and firmware version 
18.168.6.1
