I can confirm I'm having the same problem with a Dell Precision 5510
laptop.  I have traced the problem to the startup item "/usr/lib/x86_64
-linux-gnu/cinnamon-settings-daemon/csd-xrandr"   it seems xrandr is
freezing the system when it boots up connected to a Thunderbolt 3 Dock.

If I disable that startup item, I can boot up while docked just fine, I
just can't change my monitoring configuration around.  If I boot up
using the 4.15.0-43-generic kernel, that startup option works just fine
and everything works.

Somehow linux-image-4.15.0-44-generic  has changed how the video card
works with Dell laptops and Thunderbolt 3 docks; as soon as xrandr tries
to fully initialize the graphics cards everything freezes up.
