Using driver `i2c-piix4' for device 0000:00:14.0: AMD KERNCZ SMBus

Probing for `National Semiconductor LM82/LM83'...           Success!
    (confidence 6, driver `lm83')

Driver `nct6775':
  * ISA bus, address 0x290
    Chip `Nuvoton NCT6798D Super IO Sensors' (confidence: 9)

Driver `lm83':
  * Bus `SMBus PIIX4 adapter port 1 at 0b20'
    Busdriver `i2c_piix4', I2C address 0x2a
    Chip `National Semiconductor LM82/LM83' (confidence: 6)

To load everything that is needed, add this to /etc/modules:

If you have some drivers built into your kernel, the list above will
contain too many modules. Skip the appropriate ones!
