You probably don't have any LM75's on the board, those devices at 0x48 and 0x49 are parts of the w83782d. For some reason our "alias detect" is not recognizing that. See if not inserting the lm75 driver helps. Rick F Nicholson wrote: > > Did some more investigation. It appears that there are an lm75, an w83782d and > the DIMM eeproms on the bus.
