I will try that tonight. I need this machine to work.
I have a little bit more information. After a full day of not using the dock, it worked for a few minutes this morning. Then it stopped again.
I’m seeing messages like this:
Jul 09 09:51:35 amd13 kernel: usb 1-2-port4: attempt power cycle
Jul 09 09:51:26 amd13 kernel: usb 2-2-port3: attempt power cycle
It appears that both USB-C devices I have plugged in (only one is providing power, the other is passive hub), are flapping. Connecting and disconnecting, every 3 to 5 seconds.

I will definitely try the older kernel after work today and report back.
