Using FC6+updates+updates-testing

On a DELL Precision 390 with Intel Core 2 Extreme X8600 cpu
Latest DELL BIOS 2.0.8 for Precision 390.

I get ">>> ERROR: Invalid checksum" in ACPI as shown below.

I really don't understand the consequences of this error. Is it related
to bios-kernel interaction. Please advise.

Thanks
