VirtualBox piix4_smbus Error
VirtualBox 3.2.10 gives me the following error message when booting Ubuntu 10.10:-iix4_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
