On my HP dc7600U the last messages printed are: PCI: BUIS Bug: MCFG area is not E820-reserved PCI: Not using MMCONFIG Googling I found a message about a IBM laptop reporting this message but that it did go on to boot. THere was a suggestion that the test should be removed. I commented out the code and I can boot further. Here is the code I patched. --- arch/i386/pci/mmconfig.c~ 2006-06-15 13:04:58.000000000 +0100 +++ arch/i386/pci/mmconfig.c 2006-06-15 13:04:58.000000000 +0100 @@ -194,17 +194,19 @@ if ((pci_mmcfg_config_num == 0) || (pci_mmcfg_config == NULL) || (pci_mmcfg_config[0].base_address == 0)) return; +/* qqq if (!e820_all_mapped(pci_mmcfg_config[0].base_address, pci_mmcfg_config[0].base_address + MMCONFIG_APER_SIZE, E820_RESERVED)) { printk(KERN_ERR "PCI: BIOS Bug: MCFG area is not E820-reserved\n"); printk(KERN_ERR "PCI: Not using MMCONFIG.\n"); return; } +qqq */ printk(KERN_INFO "PCI: Using MMCONFIG\n"); raw_pci_ops = &pci_mmcfg; pci_probe = (pci_probe & ~PCI_PROBE_MASK) | PCI_PROBE_MMCONF; Barry
