Yes, the usual mess: ofed X is based on kernel Y1 but with some additions from kernel Y2 plus plenty of unreviwed and non-merged patches. Distro Z picks ofed X and the result is 99% unsupportable as Roland said. Somehow this ofed creature is still hanging around working on the the next damage its going to bring into this world (code name 1.5)

Eli, here's a little tip for you, I had the displeasure to resolve bunch of support cases originating from the fact that the below 2 years old commit missed some ofed version (sorry forgot the number...), maybe it would help you as well?

Under a normal setting, if this commit actually solves a bug being hit by many costumers, someone would have opened a distro bugzilla case saying, "please pick this commit for your kernel", the customers would have either wait for the next distro update or use a distro intermediate kernel. Currently, I understand that distros are picking ofed versions and that's it.

Or.
