Are you sure you are measuring the >correct thing and that ACKs are matching the right data packets ? This project was realized by some students here at Technical University of Berlin. They told me now, they used a 12.88 MHz crystal (divided by 2) as the (nominal 5 MHz) clk for the two c011. This works properly, because we never wanted (or tried) to connect this link-adaptors to other Inmos Devices and due to the superb Inmos chips... . I'm sorry about the confusion.
