** Description changed: 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. + As you can see from the linked question and forum thread, this appears to be affecting many Dell tablets and laptops.
