You have that in your ASL:

            OperationRegion (TMEM, PCI_Config, 0xC4, 0x02)
            Field (TMEM, ByteAcc, NoLock, Preserve)
            {
                    ,   3,
                TOUD,   13
            }

            Name (TOM, 0x00)
            Method (MDET, 0, NotSerialized)
            {
                If (TOM) {}
                Else
                {
                    If (FLAG)
                    {
                        ShiftLeft (TOUD, 0x13, TOM)
                    }
                    Else
                    {
                        Return (0x20000000)
                    }
                }

                Return (TOM)
            }


I am pretty sure that the root of your trouble is
the 'ShiftLeft (TOUD, 0x13, TOM)'.
(For info, FLAG is declared as Name (FLAG, 0x01), so
that is not the problem as well).

I think it is valid, and suspect more or less there is
a bug in ACPICA.  But I am not sure.  If a guru
can help me to determine that I am right or wrong (Bob?).
