radupantiru@: Your MCFG says there's ECAM space at [mem 0xf8000000-0xfbffffff] for [bus 00-3f]. That space *should* be reserved via a PNP0C01 or PNP0C02 device in the ACPI namespace, but it isn't, so this is likely a BIOS defect.

Can you try the patch I attached here? https://bugzilla.kernel.org/show_bug.cgi?id=218050#c6 . If you can, please attach the dmesg log here.
