Thunderbolt dock authorized, but not working


recently my thunderbolt-3-dock stopped working.
I am not sure, what the main cause could be. Meanwhile there was a bios update, which could be a good cause-candidate btw.

I connected, authorized (boltctl) and removed the device multiple times, tested different thunderbolt-security settings, but nothing worked.
Only the external display is working, connected over displayport.

In Windows the dock still works as expected.

Is there some kind of another "reset" I could try, to make it work again?

So it turns out, that it is got something to do with the latest BIOS update (114).
But no one knows, what exactly causes the issue.

Can you maybe take a look at the output of dmesg and see anything thunderbolt related after you try to connect/configure/etc. the device? If you run dmesg -w, you can see the kernel message buffer in real time, so that way it might be easier to know which messages appeared when you did something.

Sorry, I encountered your comment only now...
The output of dmesg, when connecting/disconnecting the thunderbolt dock is just this:

[18898.693324] pcieport 0000:00:1b.0: EDR: ACPI event 0x2 received
[18939.945435] pcieport 0000:00:1b.0: EDR: ACPI event 0x2 received

And does the device appear anywhere in the settings after you connect it?
