After most recent kernel update (4.15.0-44-generic) my tablet freezes whenever plugged into docking station
I performed the most recent kernel update on my Dell 5290 2-in-1 earlier today. But moments after I plug it into its docking station, the screen flickers, blanks and freezes. The only item left on the screen is the mouse pointer, and it is stuck.
If I leave the tablet not plugged in, it runs just fine. It seems to be the docking station that triggers the freeze.
That said, I can log into the tablet via ssh even with the screen frozen. So the system is still running. But if I try to reboot the tablet via the "reboot" command, nothing appears to happen.
Any ideas where I should start looking to identify this problem?
edit: "sudo reboot -f" will reboot the system, while "sudo reboot" will not.
