More likely you updated the driver; the new nct6775 driver handles the various sensors on the chip differently. The AUXTIN value suggests that either nothing is connected to the input pin, or that the wrong sensor type (eg diode vs. thermistor) is selected. Most likely nothing is connected to it. The mappings for temp6/7/8 are pretty common for Intel boards.
