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