Hi,
i'm not sure if i understood the new acpi xen cpufreq driver - here's the
output when loading xen_acpi_processor module in linux 3.4:
dom0 dmesg:

Can you include your xl dmesg and dmesg and as well
the /sys/firmware/acpi/tables/DSDT and /sys/firmware/acpi/tables/SSDT*
files please?
Does xenpm work properly?

xenpm works - at least "xenpm get-cpuidle-states" and "xenpm
get-cpufreq-states".
here you can find my acpi-tables including "xl dmesg" and "dmesg" output:

So your DSDT has:
External (\_PR_.CPUF, DeviceObj)
External (\_PR_.CPUE, DeviceObj)
External (\_PR_.CPUD, DeviceObj)
External (\_PR_.CPUC, DeviceObj)
External (\_PR_.CPUB, DeviceObj)
External (\_PR_.CPUA, DeviceObj)
External (\_PR_.CPU9, DeviceObj)
External (\_PR_.CPU8, DeviceObj)
External (\_PR_.CPU7, DeviceObj)
External (\_PR_.CPU6, DeviceObj)
External (\_PR_.CPU5, DeviceObj)
External (\_PR_.CPU4, DeviceObj)
External (\_PR_.CPU3, DeviceObj)
External (\_PR_.CPU2, DeviceObj)
External (\_PR_.CPU1, DeviceObj)
External (\_PR_.CPU0, DeviceObj)
And along with some other stuff in the DSDT it advertises that
it has 16 CPUs and it sets up even sixteen _CST and _PST data structures.
But you only have eight. This is really a BIOS bug.
However, let me fix it in the driver so that you don't get that error.
(I had a similar fix in the driver for dealing with the P-states
but didn't do it for the C-states).
