> ACPI: CPU0 (power states: C1[C1] C2[C2])
this is likely a case of a C-state (C2) exported by the platform
that returns immediately rather than actually entering idle.
you should be able to make the symptom go away with
processor.max_cstate=1
Please verify that you're running the latest BIOS for the system.
Sometimes vendors get this wrong on release and then correct it...
Then please check the BIOS SETUP for any options related to
processor power management.
However, what we really want to know is why C2 isn't working...
please attach the output from acpidump so we can see
exactly what C-states the system claims to support.
