We have to write to standard I/O ports to probe them. This is usually safe. Do you want to scan for Super I/O sensors? (YES/no): Probing for Super-I/O at 0x2e/0x2f Trying family `National Semiconductor/ITE'... Yes Found unknown chip with ID 0x0404 I have tried to search on the motherboard but didnt find any visible NS nor ITE chip. (could it be embeded in chipset or BMC for example ?) Furthermore, with another OS (a buildroot with more recent kernel), sensors-detect give that the ID is 0x0101. Any hope there is a real hwmon chip behind ? Regards
