I'm having the same issue on a Dell Latitude 5289 laptop connected to a dell USB-C dock with 2 external monitors, and USB keyboard and mouse (Razer Naga Chroma). My computer will immediately lock up upon pressing Super + L to lock the screen when it's connected to the dock. When disconnected from the dock, it wakes up fine. This is isolated to 4.15.0-44 for me as well. I am unable to replicate in 4.15.0-43.
