It is really and truely an ie1.

If this is really a problem that should ocaisionally occur,
can we get it off the console stuff? I'd really rather only get
messages there that matter to me or indicate a serious problem (by the
frequency and manner of this error, it seems like we'd get the same
value by warning about collisions on the console).

This is a 4/260. It does not have an Sbus.
