I'm trying to track down a problem by using systemtap - but it needs the
debuginfo for the affected modules, and the OFED installer does not create a
debuginfo for the kernel modules.
Is there a way to turn the creation of debuginfo files on?

You really don't want to use ipoib for HPC applications. What MPI are you
