Thanks. The above commit was backported to several stable series,
relevant for Debian are 5.10.200, 6.1.62, (6.5.11) and 6.6.1.

Is the issue as well reproducible with the kernels 6.5.13-1 in
testing, 6.6.9-1 in unstable?

With those datapoints it might now be good if you can report it to
upstream. Contact point would be the people from the issue introducing
commit, expanded with the linux-pci@vger.kernel.org and
linux-kernel@vger.kernel.org lists.

Regards,
Salvatore
