RE: [ACPI] acpi_serialize not working?

[Moore, R. <rob...@in...>]

The implementation of the forced serialization is straightforward:

    if (AcpiGbl_AllMethodsSerialized)
    {
        ObjDesc->Method.Concurrency =3D 1;
        ObjDesc->Method.MethodFlags |=3D AML_METHOD_SERIALIZED;
    }

I would be interested in more information on the failure.
