During booting up to my Ubuntu, after about 20 seconds of black screen with blinking cursor. I get the message:

gpio_ich: failed to claim resource 0

This makes my boot very slow.

Does anyone know what this is?

This happened to me both with my Ubuntu 12.10, and my Ubuntu 13.04

In my kern.log, I see this error twice. Here is my kern.log a few lines before and after the errors:
