Description

The following messages are repeated for every CPU core when SpeedStep/PowerNow! support is disabled in BIOS, and while it's not really a bug, it's getting pretty annoying and spams the log with useless information.

Intel SpeedStep:

Aug 17 07:22:56 sirius unix: NOTICE: cpu_acpi: _PSS package evaluation failed for with status 5 for CPU 0.
Aug 17 07:22:56 sirius unix: NOTICE: cpu_acpi: error parsing _PSS for CPU 0
Aug 17 07:22:56 sirius unix: NOTICE: SpeedStep support is being disabled due to errors parsing ACPI P-state objects exported by BIOS.

AMD PowerNow!:

Aug 17 07:24:42 altair unix: NOTICE: cpu_acpi: _PSS package evaluation failed for with status 5 for CPU 0.
