I have reported this bug at the openfabrics bugzilla as well already. They have already identified the issue and I created a patch to fix it. Please patch future kernel versions with this fix. http://bugs.openfabrics.org/bugzilla/show_bug.cgi?id=2427 I've attached the simple patch to resolve this problem.
