I already did, but here again in detail: Intel 9x5 hangs when you do any mmconfig access (apparently reference BIOS fills in bogus address). Check against ACPI resources doesn't catch it either. Mac Mini doesn't do any Type1 at all, so a verify pass that checks mcfg against type1 doesn't work there. AMD K8 boards with PCI-E bridges have mmconfig only on some busses, but not on the internal northbridge busses. MCFG can describe this by listing segments, but the contents of that on many boards can be described as "fictional" at best. That is why Linux needs to verify that too. > All I have to do on my machines is work around the disable-mmconfig > code, and things start working. If the choice is between a secret NDA only card with dubious functionality and booting on lots of modern boards I know what to choose. -Andi - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
