Not sure if this is related to the linux kernel to fix up the Pluggable UD-4VPD
dock https://www.spinics.net/lists/linux-usb/msg263475.html.

The kernel running is the latest from here AUR (en) - linux-mainline-um5606
https://aur.archlinux.org/packages/linux-mainline-um5606. It is based on the
6.13 kernel. It adds some patches as this laptop has been a bit unstable.
Hence, the additional amdgpu boot parameters.

thunderbolt.dyndbg=+p output shows the issue starting at time 27.027128 in the
attached dmesg
