Comment 9 for bug 1902469

This is the closest match I could find to the problem I'm experiencing. Every Kernel update above 5.4.0-59-generic on Ubuntu 20.04.1 LTS on this Thinkpad T580 docked on the Thinkpad Ultra Docking Station causes the computer to freeze up either just before the login screen, on the login screen or shortly after successful login. If I take the machine off of the docking station, everything works fine. Docking and removing external monitor connections does not make it any better.

Sorry if I'm not in compliance with this forum's practices. I'll go read-up on that and get in line ASAP.
