I performed all my tests with the in-box drivers, which I thought the community would be interested in. I _also_ ran my tests on the Mellanox OFED driver to see if it was something specific to the in-box drivers or consistent across both as an additional point of information to help with resolving the problem. The problem shows up in the in-box driver and the Mellanox OFED although a little different.
