Added printfs()

    printf("before setforeach\n");

    SET_FOREACH(nd, nexus) {
        printf("setforeach: %s\n", nd->name);
        device_add_child(dev, nd->name, nd->unit);
    }

Got only 'before setforeach' in console. So it doesn't step into loop.
Any ideas? Also I already had printfs in my driver's probe and attach,
also got no output.
