--- Comment #6 from Zhang Rui (rui.zh...@intel.com) ---
In dsdt WT1A device object is defined under \_SB.I2CA
        Scope (I2CA)
        {
            Device (WT1A)
            {
            ...
            }
        }

However, in ssdt3

    Scope (\_SB.I2CA)
    {
        Device (WT1A)
        {
        ...
        }
    }

It is redefining the \_SB.I2CA.WT1A object.

That is probably because Windows never dumps these messages...

I don't know if the above helps or not.

I don't know, this could cause problem to some I2C devices.
