Despite the encouraging information from @Gabriel Mateiciuc, I'm still not 100% sure the 1.8.2.5 drivers actually work on 6.5. According to my past experience, as well as other people's posts on Mellanox Communities and, most importantly, Mellanox themselves, they don't and they shouldn't. I'm a bit reluctant to give it another go, because my current environment is stable and I don't really have the time to fiddle with it.
Any volunteers to give it a whirl and post some solid results?
