Do you mean they should work with the latest infinipath libraries
(despite what it said or implied in the notes for last version I got
from QLogic?) or possibly what's in RHEL? I thought I'd actually tried
and failed with later stuff, but may just have gone by the release notes.

I wonder if there's a version of the driver that's known to work in a
current RHEL5 system with QLE7140. We get frequent qib-related kernel
panics from a vanilla RHEL5.9 kernel -- after running OK under test for
a few weeks, and nothing relevant appearing to have changed to cause
it... (There's a trace on the redhat bugzilla with qib in the issue
title, for what it's worth.) I'm currently reverting to old stuff.
It's good if Infinipath-land is taking an interest in OMPI again, and
that the libraries are now under a free licence.
