Hmm, I guess you don't need to try each combination of  THM[0267].
>From pervious experience, we know _THM0._TMP causes problem.
If you fake _TMP for all THM, what could happen?

If you verified _TMP cause issue by fake them in DSDT,  probably,
we need to continue dig Method : UPDT. 

                    Method (UPDT, 0, NotSerialized)
                    {
                        If (IGNR)
                        {
                            Decrement (IGNR)
                        }
                        Else
                        {
                            If (H8DR)
                            {
                                If (Acquire (I2CM, 0x0064)) {}
                                Else
                                {
                                    Store (I2RB (Zero, 0x01, 0x04),
Local7)
                                    If (Local7)
                                    {
                                        Fatal (0x01, 0x80000003, Local7)
                                    }

                                    }

                                    Release (I2CM)
                                }
                            }
