That is exactly it. The relevant section of the debug info is PCI: Bridge 0000:00:01.0 PCI: Bridge resource 7 00008000-00008fff (%f=100) PCI: Bridge resource 8 f7d00000-fddfffff (%f=200) PCI: Bridge resource 9 bdf00000-ddefffff (%f=1201) The bridge was assigned to a piece of the end of physical memory. r~ -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
