I saw similar i2c error messages back when we were trying to add
support for the card (I never posted on the list about it because that
happened when I was fiddling with the code). I do not remember the
specifics, but it went away later on as the code matured. It might
have something to do with multiple instances of the driver being
attached to the xc5000, but we certainly cannot rule out the
possibility of a bad unit.
