Other sensors seems to be not initialised and always return some weird temp (minus 29 or smth like that). Only first sensors works. I initially started to look at this after enabling idle states on E850-96 (they work with only some un-upstreamable change). Having at least one sensor is better than nothing. I am looking at enabling ACPM thermal thingy but so far I see similar issue that temp of all sensors is reported as 10 C regardless via ACPM. Having said that I am not going to oppose this series moving forward if you wish. Thank you. Best regards, Alexey
