Hello,
Sorry, I have originally posted my question here, but I have since then found out about this forum and also upgraded the system to F38, so I thought I will ask again.
I have a Lenovo ThinkPad P1 Gen 4 with Fedora 38 installed. Kernel version is 6.3.11. I originally bought a Lenovo USB-C dock for it (40AY) and that worked fine on F37 for a while until one day, the port went completely silent. I assumed at first it was a problem with the dock and bought a compatible Thunderbolt 4 dock (40B0), but I am getting no response from it either.
It seems that my Thunderbolt 4 ports are powered on, but whatever I plug to them I get no output:
boltctl list -a

The dock is the only T4 device I have and I get a blank output from boltctl if I plug it in. I also tried plugging a standard USB-C pendrive and that doesn’t get detected either.
Running journalctl -u bolt gives me:

Which looks fine, I think?
Can you please advise how to debug this issue? I would like to eliminate the possibility that this is a hardware failure on my laptop, but I am not sure how to confirm it. Thanks.
