You might be able to get a BIOS update to support it. Does Windows manage to see extended PCI config space on this same machine? BTW, I found a machine which doesn't support MMCONFIG (and it would have been shown by your greps): [ 0.117837] ACPI: bus type pci registered [ 0.118510] PCI: MCFG configuration 0: base e0000000 segment 0 buses 0 - 255 [ 0.118517] PCI: Not using MMCONFIG.
