Hi,
thanks a lot for your answer
Now it appears that 2 boards are working and 9 do not.
All boards have the same bios version but we dont know anything about the
hardware revision. It is always the same type of board (Intel D850MV).
Please see below the output of sensors on the working board und i2cdump on
both the working and non-working board.
Regards.
Thomas
