Thanks Diederik, that did the trick! After setting "Runtime PM for PCI Device Intel Corporation Sunrise Point-LP CSME HECI #1" to "Bad" the issue went away :) I can just set it to "Bad", but it was running fine on "Good" on the previous kernels, so I guess there is still some regression here (and I don't know what this effect will now have on battery life). How should I proceed, as the bug's nature has now changed?
