My system uses graphical boot via plymouth. Dell logo remains on screen while ubuntu loads into gdm3 (when it is booting normally). I'm using LUKS. This is a regression from focal and kernel 5.4. If I boot the laptop with the thunderbolt dock connected, the system will get past the Dell logo, go to a black screen and remain there. The screen is powered up as I can see some light on the edges. It won't boot up or respond to any keys. After force-shutdown via power key long press, on the next boot the grub menu will appear. The system will boot normally then (with the dock still connected). If I boot the system with the dock disconnected, it will correctly go into disk encryption password prompt. If at that point I connect the dock and wait without entering the password, the system will correctly set up the dock: the displays lit up and the mouse and keyboard plugged into it become active. The system boots normally. I'm trying to bisect in which kernel version this happened. I'll put results in a comment.
