This issue has been proposed when we are only considering blocker
issues in the current Red Hat Enterprise Linux release.
** If you would still like this issue considered for the current
release, ask your support representative to file as a blocker on
your behalf. Otherwise ask that it be considered for the next
Red Hat Enterprise Linux release. **
On my machines, which only have mlx4 hardware in them, the libraries that include psm support exit when they fail to open /dev/ipath. Are you running your tests on machines that have ipath hardware that you aren't using?

I have unloaded ib_mthca module and loaded ib_ipath so that only infinipath devices were up and running and ran openmpi.
I wonder if you didn't have libipathverbs and infinipath-psm packages on ?
Red Hat Enterprise Linux 6.0 is now available and should resolve
the problem described in this bug report. This report is therefore being closed
with a resolution of CURRENTRELEASE. You may reopen this bug report if the
solution does not work for you.
