Yes. At a closer look I realized that cross-link.c does set it's own
configuration. Therefore I have a few questions:

- do you use an *unmodified* version of cross-link.c?

- What Xenomai version do you use?

- What Linux kernel version do you use?

- How do you build "cross-link"?

And please do not drop the CC to the list.

Wolfgang.
