That's weird, I would not expect a behaviour change in the latest
patch. pci_restore_config_dword() has some debug messages, could you
please make them visible and show logs again?
Also remind us of the PCI device address of the parent bridge (lspci -vt)
I'll follow up with more the requested information on bugzilla
(Link: https://bugzilla.kernel.org/show_bug.cgi?id=201069).

On a quick re-check, it seems to depend on if I used the eGPU before
the initial suspend. If I run glxgears (with DRI_PRIME=1) before suspend 
it seems fine.

Best regards.
