Maybe rt_dev_accept is not properly wired up in RTAI user land though it should simply translate to an IOCTL on the rtnet fd. Check the call path, specifically if RTnet receives the IOCTL in rt_tcp_ioctl. > 2.

If I issue a rt_dev_shutdown() on a UDP socket, I get an "Ooops' output. Our UDP does not implement shutdown, but you shouldn't get an oops. Again, we need backtraces (frame pointers enabled, please). Jan
