With that changed to host = pci_get_device(PCI_VENDOR_ID_INTEL, 0x0154, NULL); and a bit of debugging code, it says now: [ 0.235739] quirk_intel_haswell_mch: entry [ 0.235800] quirk_intel_haswell_mch: got host: 0x0 [ 0.235860] quirk_intel_haswell_mch: mch: [mem 0xfed10000-0xfed17fff] [ 0.235930] quirk_intel_haswell_mch: res: [mem 0xfed10000-0xfed13fff] [ 0.235990] pnp 00:01: [Firmware Bug]: [mem 0xfed10000-0xfed13fff] covers only part of Intel Haswell MCH; extending to [mem 0xfed10000-0xfed17fff] So you probably want to have a list of hostbridge pci ids in the quirk or so.
