Upgraded firmware on mellanox infiniband connectx hardware and got following spam in system log.

[ 1680.962538] DRHD: handling fault status reg 302
[ 1680.967048] DMAR:[DMA Read] Request device [04:00.6] fault addr f647a000
[ 1680.967049] DMAR:[fault reason 02] Present bit in context entry is clear

This also broke infiniband on f13/f14 machines. I used the iommu workaround described above, and infiniband now works.

RHEL6.0 doesn't exhibit this problem with the updated firmware:

Linux mrg-03.mpc.lab.eng.bos.redhat.com 2.6.32-131.0.15.el6.x86_64 #1 SMP Tue Mx

Is this a kernel.org regression?
