Interesting, we use GPFS over IPoIB and upgraded to RHEL 6.6 in early
November and haven't seen any issues at all (and with a lot of
bioinfomatics users we'd notice problems pretty quickly).
Is your IB running in connected mode or datagram mode?
We're in connected mode everywhere because of our BG/Q.
