The machine apparently seems to start fine in case it is undocked. (Don't know why I didn't try that out before.) My dockingstation is a Lenovo 40AS in case that matters.

After updating the Kernel to a version above 5.15.0-48, the system didn't start. I therefore used the old one (Version 5.15.0-48) from the recovery menu - the machine boots again. I believe that this information is not enough to assess the problem. I see some error messages even when the machine boots correctly. Could anyone please tell me what I should try out or read out to get more information?
