Hi,
when I try to connect my Laptop with my Dell docking station via USB-C, in most
cases the external monitors (connected via the dock) do not turn on. I have to
plug and unplug many times before it eventually works.
The machine is a fairly new Thinkpad with AMD Ryzen AI 7 PRO 360 w/ Radeon
880M.
Usually, I see this message on failure:

Your issue forwarded to
https://gitlab.freedesktop.org/drm/amd/-/work_items/4384 should in
meanwhile be fixed (fixes in 7.2-rc7 and 7.1.8).
I will close the bug with the respective versions, but please feel
free to reopen if that turns out to not be the case.
Regards,
Salvatore
