Why should what order the connectors get set up matter? If it's supposed
to matter, has this been tested in anything other than this guy's
particular configuration to make sure that you're not regressing other
If I had to take a wild guess, this would be another manifestation of
the failure of the SDVO code to have a single encoder instance managing
the multiple connectors attached to it, so the different connectors
fight over the state of the encoder.
