several devices PCI bar doesn't get assigned from BIOS.
after several times retry, mmio ranges get assigned, but io port range can be allocated enough range. it needs 16k,
but under 05:01.0 to 08:00.0 and 09:04.0 orginal io port from BIOS allocation get lost.
wonder be good, if We can restore it for such case.
current may have to disable bridge resizing feature by default.
can you send out
