some news . I lurned that the message "ACPI: Unable to turn cooling device [dffdfdec] 'on'" is linked to the module "thermal". I checked it disappears after "sudo modprobe -r thermal".
Something is quite strange. After a reboot , the removed thermal module is not there ( not in the list provided by lsmod ) but the error message reappears ... and disappears again after a "sudo modprobe -r thermal".
