Probably because you run a distribution where someone stupidly blacklisted i2c-i801 because it caused trouble on one single machine once. And you should report this as a bug. > At that point I ran sensors-detect, which failed to recognize any known > controllers on the bus, but i2c-detect found several addresses that > responded.

All recent desktop boards from Asus implement an ACPI device named ATK0110 for hardware monitoring, which is supported by the asus_atk0110 driver. So if all you are interested in is hardware monitoring, that's the way to go. If you really want a complete analysis of what may be on your SMBus, please share the output of i2cdetect with us. You can get register dumps from most devices using i2cdump, however I would NOT recommend doing this on all addresses randomly, as some devices are known to misbehave when accessed in a way they do not expect. -- Jean Delvare -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
