I left "ibv_rc_pingpong -n 10" running in a loop between two of my
machines with no problems, so there's something specific to your setup.

When you say "latest openib code," what does this mean?  Are you
running something from subversion or a standard Linux kernel?  Do you
have 1-port or 2-port HCAs?  What HCA firmware version are you
running?
