We now have some further information on the matter as somebody was kind
enough to bisect the issue in the [Arch Linux Forums][0]:

    cc4c94a5f6c4 ("thunderbolt: Reset topology created by the boot firmware")

This is a stable commit id, the relevant mainline commit is:

    59a54c5f3dbd ("thunderbolt: Reset topology created by the boot firmware")

The other reporter created [a issue][1] in our bugtracker, which I'll
leave here just for completeness sake.

Reported-by: Benjamin Böhmke <benjamin@...hmke.net>
Reported-by: Gia <giacomo.gio@...il.com>
Bisected-by: Benjamin Böhmke <benjamin@...hmke.net>

The person doing the bisection also offered to chime in here if further
debugging is needed!

Also CC'ing the Commitauthors & Subsystem Maintainers for this report.

Cheers,
Christian
