Re: Illegal instruction signal at startup. (with net-rs6k smp)

It is a little hard to find out anything wrong here. I would suggest build
your own binary (there may be binary or library incompatibility problem).
For more options, you can try net-rs6k (without smp) or MPI version
like mpi-sp|IBM-SP.
