The reason you see this message is b/c your machine implements MMCONFIG. Unfortunatly, some Intel motherboards implemented this wrongly and Linux kernel would crash. To boot up on those boards without crashing, the kernel checks to see if the address specified in the ACPI MCFG area is also reserved in E820 area (which btw, is not something the ACPI v3.0 and PCI Express spec mandates - it is optional). This is short-term fix and once a better solution is found the mainline kernel will have that (and FC will have it too) So for right pls ignore it. It should eventually go away when main-line finds a proper fix. |
