If you see the following error message when booting Arch Linux:
==
piix4_smbus 0000.00.07.0: SMBus base address uninitialized - upgrade bios or use force_addr=0xaddr
==
To fix this, add "blacklist i2c_piix4" to file /etc/modprobe.d/modprobe.conf
/etc/modprobe.d/modprobe.conf
==
blacklist i2c_piix4

'SMBus base address uninitialized '
