[转]解决Ubuntu的问题："SMBus base address uninitialized

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

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 :-

# sudo vim
在最后一行添加：
blacklist i2c_piix4

3. Update the initramfs

# sudo update-initramfs -u -k all

The prompt will return something like
update-initramfs: Generating /boot/initrd.img-2.6.35-22-server
