No, this suggestion of mine was unrelated. > Could this be the reason why my I2C adapter isn't instantiated? No. If the driver is properly build in, then I suspect that the device itself is missing. Just check in /sys/devices/platform/ if it's there or not. If not then something's missing in your machine init data. -- Jean Delvare http://khali.linux-fr.org/wishlist.html _______________________________________________ lm-sensors mailing list lm-sensors@lm-sensors.org http://lists.lm-sensors.org/mailman/listinfo/lm-sensors
