Actually, I think it's probably complaining about tag reuse in the sense of SAM-3 section 5.9.3. You return this sense if an initiator attempts to use a duplicate tag. Since the aic79xx manges its own tags, then it's probably a driver error. You could verify this by having the aic79xx print out the tag as it sends the command out on the wire. (The device does support TCQ, doesn't it?)
