VirtualBox piix4_smbus Error

 
VirtualBox 3.2.10 gives me the following error message when booting Ubuntu 16.04:-
piix4_smbus 0000.00.07.0: SMBus base address uninitialized - upgrade bios or use force_addr=0xaddr

 

This error is caused by VM having no smbus but Ubuntu always trying to load the module. It doesn‘t affect anything but is a bit annoying - to fix...

1. CHECK MODULE IS BEING LOADED

lsmod | grep i2c_piix4

2. IF SO, BLACKLIST IT IN /ETC/MODPROBE.D/BLACKLIST.CONF, BY ADDING THE FOLLOWING TO THE END OF THE FILE:-

blacklist i2c_piix4

3. UPDATE THE INITRAMFS

update-initramfs -u -k all
