Sorry about that; it's a problem down in the kernel/driver stacks.
Note that if you're using the IB support that comes with LAM/MPI,
this means you're likely using an mVAPI-based IB kernel stack. You
might want to investigate upgrading to OFED (the OpenFabrics
Enterprise Distribution IB stack). It's open source and is where all
new work related to HPC is occurring in the IB vendor arena.
For example: http://www.open-mpi.org/faq/?category=openfabrics#vapi-
support (note that "OpenIB" is the older/deprecated name for the
OpenFabrics project).
