I do not see a deadlock, when applying the following old patch:
https://lore.kernel.org/linux-pci/908047f7699d9de9ec2efd6b79aa752d73dab4b6.1595329748.git.lukas@xxxxxxxxx/
after merge for the kernel 6.2.0-rc5, and applied the alternative patch:
https://patchwork.kernel.org/project/linux-pci/patch/3dc88ea82bdc0e37d9000e413d5ebce481cbd629.1674205689.git.lukas@xxxxxxxxx/

I have uploaded the merged patch and the system log for the upstream kernel.

You're now getting a different deadlock.  That one is addressed by this
old patch (it's already linked from the bugzilla):

If you apply that patch plus the new one, do you still see a deadlock?
