Hmmm... You are running an old kernel. What version of OFED do you
use?

Hah, if you think my kernel is old, you should see my userland
(RHEL5.5). ;-)

My condolences.

Does the version of OFED impact the kernel modules? I am using the
modules that came with the kernel. I don't believe that libibverbs or
librdmacm are used by the kernel's socket stack. That said, I am using
source builds with tags libibverbs-1.1.6 and v1.0.16 (librdmacm).

OFED includes kernel modules which provides the drivers that you need.
Installing a new OFED release on RH5 is possible and would give you up to
date drivers. Check with RH: They may have them somewhere easy to install
for your version of RH.
