With another patch pending for 2.6.24, to validate the MMCONFIG aperture against the ACPI motherboard resources instead of the E820 table, we have to delay switching to MMCONFIG until the ACPI interpreter is available (unless no other configuration mechanism is available). It might thus be feasible to delay it further. Nevertheless, I think this is a rather ugly workaround for the underlying problem. -- Robert Hancock Saskatoon, SK, Canada To email, remove "nospam" from hancockr@nospamshaw.ca Home Page: http://www.roberthancock.com/ - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
