Thanks for the detailed description! There was follow up patch that made
the timeout shorter for slow links, I wonder if you could try that first
and see if that changes anything? It is this commit in the mainline:

7b3ba09febf4 PCI/PM: Shorten pci_bridge_wait_for_secondary_bus() wait time for slow links

That should at least make the resume faster too but let's see.
