Bug Description

This morning I upgraded to Kubuntu 21.04.

I use two external monitors connected to my Dell XPS laptop via a Dell WD19 dock.

Post-upgrade the monitors and also network functionality through the dock appear to have completely stopped functioning.

When the dock is plugged in and the computer is booted the monitors do not enable.
When the dock is not plugged in the computer boots normally.

When I look at the dmesg output there appears to be some notable errors when I plug the dock in:

With the dock plugged in:

* neither monitor displays although they are present under display configuration
* since my laptop screen is not usually on if both monitors are present on the dock the immediate result was no display at all under the dock was detached
* network connectivity is not established although the network device appears under networks

Unfortunately I lack the skills to diagnose this further without assistance or to install a more recent kernel to see if it is resolved there.

It appears that communications between the laptop and the Dock are not going well to my eyes (is this what link training is on Thunderbolt)

I'm happy to provide further information... although in a few days the lack of Dock and monitors will be a bit of an issue and I may have to roll something back.

Some functionality still appears to work correctly -- headphones plugged into the Dock appear to function.

When I boot to use an older kernel, initially things appear no better -- no monitors except the laptop and after logging into Kubuntu no monitors at all.

After removing the USB-C connection and plugging it back in again both monitors come back, headphones work but the wired network connection does not work.

Here's some dmesg output for this:

I should note that the AER PCIe Bus Errors have been present I think for many years and versions of Ubuntu so I think they are unrelated. However the power state transition from "D3cold to D0 (config space inaccessible)" is I think new.

Happy to provide further information.
