The fact that it's only happening on one ROACH seems to suggest a hardware fault. Perhaps try a different port.
Reprogramming the FPGA is a "hardware reset" since it's the only part of the system that keeps any state relating to 10GbE. If you re-ran the tut2 script then it would have killed and restarted tgtap which is the only software part that keeps any state.
