I've gotten similar problems on a linux Xeon cluster with ethernet, and mpich2-0.96p2. I ended up just using mpich-18.104.22.168. Both were compiled from source with gcc(for c mpi programs). With version 2-0.96p2 I could not get any sample program to run on more than a single node(which incidently worked), even those that just initialize MPI and don't do any real message passing.
Which version are you using?
