Bug Description
I have a Dell 5290 2-in-1 tablet that has been running Ubuntu 18.04 successfully for several months. Today I upgraded the kernel from 4.15.0-43 to 4.15.0-44. The tablet functions normally until it is plugged into its docking station, then the screen freezes.
Technically, the screen flickers a few times, then goes blank, leaving only the frozen mouse pointer. The system is still running, though as I can ssh into my tablet. sudo reboot will not reboot the tablet, but sudo reboot -f will.
When I force the tablet to load 4.15.0-43, the tablet functions normally. i.e. even when I plug it into its docking station, it continues to perform properly. It's only with 4.15.0-44 that it freezes.
As you can see from the linked question and forum thread, this appears to be affecting many Dell tablets and laptops. It also appears clear that the bug is not present in 4.15.0-43.
