Hmm... I think Peter Bogdanovic was hitting this error recently (cc'd). There are a lot of PRIMITIVE_RECVD messages in the log, which make me wonder if the expander is being flaky or something? The commands that start timing out under heavy load followed by the repeated broadcasts might be indicative of that, since the sequencer firmware and the kernel driver are up to date. Unfortunately, I don't have any LSI expanders... --D
