FWIW I am seeing this also with my Lenovo X1 Carbon 6th when docked to my Thinkpad Ultra Docking Station (that has 2 external monitors connected to it). This booted fine on focal but after upgrading to Groovy (or doing a fresh install) the boot hangs as soon as the plymouth splash screen tries to display. Setting nospash in /etc/default/grub (GRUB_CMDLINE_LINUX_DEFAULT) works around this for now by disabling the splash screen.
