igb watchdog timeouts

Ok... I got my wires crossed: our first time testing 8.1 on this
particular platform was with a kernel that had ichwd enabled (a new
thing for us) and so when igb started complaining about "watchdog" we
thought it was related.
We've tested again and clearly the real story is that we're simply
seeing igb issues, symptoms similar to those described.
Does 8.2-RC1 have sufficiently "latest" code, or should I be looking to
load up something else? (8-stable, maybe?)
Thanks,
Charles
