it might help you to diagnose the problem better, if you read through the
thread I pointed on (its very short, four messages, let then two minutes),
you would see that Arthur is reporting on the lap_state and Sean is suggesting to use the IB CM sysfs counter to further debug this. I don't know if these counters exist on the IB stack used for the ofed drop you're using, but they should be in 1.5.x

Or.
