I just would like to add that I have the same problem about once a day on a DELL Latitude E5550, usually a relatively short while after resuming from standby. It never happens when I boot into the older 4.15.0-39-generic kernel.
On a Lenovo L420 that I have updated at the same time, I never had the problem so far.
