SCSI behind PCIE bridge only detected using pci=noacpi

Should this work or is this really not supported via ACPI?

I expect this is the relevant output:

ACPI: PCI Root Bridge [PCI1] (0001:40)
PCI: Multiple domains not supported
ACPI Error (pci_root-0279): Bus 0001:40 not present in PCI namespace<7>Losing some ticks... checking if CPU frequency changed.

With pci=noacpi the SCSI disk/controller works fine. Without even the controller is not recognised.

IIRC, -mm tree has the x86 multiple domains support patch. Without that patch all pci devices of non-zero domains can't be found.
