When i have either my Thinkpad X1 or my Dell Latitude 7450 connected to a Dock and turned off and i want to start them via my Dock or open the Lid and press the Start Button on the Laptop itself, it Starts Booting and then before loading the Login Screen it will turn into a infinite loading screen, when i unplug the dock and force the device to turn off and restart it without having it plugged in the Dock it starts without issues, my Dock at home is a Lenovo Smart Dock 5 but this issue also happened with a different Lenovo Dockingstation at my Workplace

Research direction

Start with the linked CachyOS log and reproduce the boot sequence with each Lenovo dock connected, then compare it with an undocked boot on the listed laptops. Done means the system reaches the login screen and allows login when booted from either the dock or laptop power button.
