The warning just indicates that you have a multi-cpu system but that your ACPI AML didn't provide a _CST method. This is a harmless warning and the cpu driver will revert to using the previous method to change the Cx states). This will probably limit you to the C1 state, ymmv. You might want to try to update to a newer BIOS version, which might include the _CST method. Regards, Steph
