No change. Most likely it fails here: err = pci_write_config_dword(hw->pdev, PEX_UNC_ERR_STAT, 0xffffffffUL); if (err) goto pci_err; PEX_UNC_ERR_STAT is 0x104; this register is outside of the standard 256-byte PCI configuration space, and is reachable only via the MMCONFIG access mechanism. Seems that kernel is not using MMCONFIG for some reason; you mentioned that you have CONFIG_PCI_MMCONFIG=y in kernel config, so it looks like your BIOS does not provide proper MCFG table. Full dmesg output might give some clues.
