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. > You can get the driver (ib_qib) and PSM library from OFED 1.5.4.1 or > the current release OFED 3.5. 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.
