The Wiki didn't reflect the upcoming version in Xenomai 2.4 yet. I
updated it, please see http://www.xenomai.org/index.php/16550A (the

What I-pipe patch are you using? I saw that Philippe uploaded new
revisions (see SVN) that may fix this issue. Please check independently
of the other issue so that we know if that problem was fixed.
