I was able to verify matching addresses for GL702VMK, X505BA, X505BP, X580VD, X542BP. I also have logs for FX502VD, FX502VE and X550VX but they only log one set of addresses, some kernel version along the way did not log both. Don't have logs for X542BA. I think this plus the code tracing is overly convincing, Reviewed-by: Daniel Drake <drake@xxxxxxxxxxxxx> Thanks.
