This line is missing below, it indicates that the kernel couldn't or
didn't power up the PCIe for some reason. We're looking for something
like ACPI or PCI patches (possibly PCI-Power management) to be the
culprit here.

This is really the only message that matters. It indicates the config
space is inaccessible, and from the system/kernel's perspective, the
device is unplugged or not responding, or in a PCIe power state.

Thank you for helping the community figure out what is up here. I don't
believe that it is a driver bug/change that broke things, but anything
is possible. :-) Given what I saw above I wonder if you should try to
boot with pci_aspm=off
The best option is a bisect using git, but it will help to narrow things
down to a couple different kernel versions if that is the only option
you have.
