Yes, that is the only reasonable thing that could happen.

init failure should only be possible under exceptional cases (OOM).

The only system response is to call ib_umad_add_one again - so of

Hopefully all these errors propogate enough so that driver insmod fails
with a perfect clean up. Otherwise it is broken :|
