A slightly annoying error message always appears whenever you boot Ubuntu 11.04 Server as a guest O/S in VirtualBox:
piix4_smbus 0000.00.07.0: SMBus base address uninitialized - upgrade bios or use force_addr=0xaddr
It doesn’t actually do any harm to the guest (as far as I can tell), so one could perfectly well leave it alone. But it’s possible to get rid of it altogether simply by issuing three commands and editing one configuration file. First:
sudo nano /etc/modprobe.d/blacklist.conf
Add the text
blacklist i2c_piix4
…to the end of the file. Finally, issue the commands:
sudo update-initramfs -u -k all sudo reboot
When the machine comes back up after that last reboot, you won’t see the error message. What this is doing is simply preventing an attempt to load the i2c_piix4 kernel module. VirtualBox doesn’t emulate the hardware for which this module is actually needed, but Ubuntu doesn’t know that and tries to load it anyway. Blacklisting the module prevents Ubuntu doing that and thus makes the error disappear.


The font you use looks like crap on Chrome.
As someone who uses Chrome almost exclusively, I think I’m qualified to say that I think you’re wrong. But thanks for your input.
Update: Turns out the use of custom fonts in WordPress blogs is due to expire on June 29th anyway (unless I agree to start paying for the privilege). So I’ve changed the theme to something a bit wider than before and lost all custom fonts in the process. Should make it clearer for you, I expect.
