Will you please try the patch in 
http://bugzilla.kernel.org/show_bug.cgi?id=12376#C45 ?
    
In fact the above message is correct. It reports the potential risk. 
The ECIO(0xcc00-cc1f) is defined in ACPI AML code and it will be accessed. In such case we had better load the I2C driver for the SMbus PCI device.

Thanks.

The patch in http://bugzilla.kernel.org/show_bug.cgi?id=12376#c45 is already shipped in acpi-test tree. 

So this bug will be marked as the duplicate of bug12376.

Thanks.
