Teo, thanks for the photo. > pci_mmcfg_read() try "pci=nommconf" if it works, then, then try the latest kernel from kernel.org to see if this is specific to ubuntu or generic to Linux. If specific to ubuntu, looks like the bug you filed there already covers it. If generic to Linux file a bug at kernel.org against drivers/pci thanks, -Len - To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
