Did you forget the attachment? Found it now. It says early in ramstage: [INFO ] PCI: Static device PCI: 00:02.0 not found, disabling it. So that's definitely an issue. But I really can't imagine how this is happening, and why this particular device. As I understand the hardware, all the decoding settings in the PCH shouldn't affect the northbridge devices. There's more [DEBUG] IGD decoded, subtracting 160M UMA and 0M GTT 0M isn't a good idea. This just prints what register settings were found. Those were probably set in romstage (compiled into bootblock with your settings if I interpreted the log correctly). It looks all very odd and alas I have no clue how it could relate to the subtractive-decode settings.
