I think more backstory would be beneficial here.. Does this happen often? What are the consequences? What are the causes? Can there be one-off invalid messages, or does that mean the firwmare has entered some unstable state? And I suppose, if answer to the last question is "unstable state", are we doing something incorrectly in Linux that causes it to happen? Konrad
