suspicious power dissipation values is a problem?

[Moore, Robert]

The warning happens when the _PSS power dissipation values are not proportional to the CPU frequency values.

    /*
     * We now know the list is correctly sorted by CPU frequency. Check if
     * the power dissipation values are proportional.
     */

        ObjDesc = Elements[1]; /* Index1 = PowerDissipation */

        if ((UINT32) ObjDesc->Integer.Value > PreviousValue)
        {
            ACPI_WARN_PREDEFINED ((AE_INFO, Data->Pathname, Data->NodeFlags,
                "SubPackage[%u,%u] - suspicious power dissipation values",
                i-1, i));
        }


The _PSS in question does not appear in the ASL file that you sent. It probably appears in an SSDT, dynamically loaded by the code below:

Load (SSDT, HNDL)

I don't know if or how you can obtain dynamically loaded tables under FreeBSD. It is possible under Linux, however.
