On my current setup 2.30.8000 <-> 2.30.8000 has been stable in ethernet mode for some time, but it probably couldn't hurt to use matching FW versions on both sides.. Also, it's been reported offlist that running large MTUs with certain (non Mellanox) switches can result in various timeouts + instability. It would be worthwhile to verify those settings on both sides as well. Mellanox folks..?
