The warning happens when the _PSS power dissipation values are not proporti=
onal 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 =3D Elements[1]; /* Index1 =3D 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 prob=
ably 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 FreeB=
SD. It is possible under Linux, however.
