...and your code still runs fine (SVN trunk, but the required patch is
in 2.2.5 as well). Moreover, stopping and restarting also causes no problem.

So, please check:

 - content of /proc/xenomai/version

If this actually gives "2.2.5":

 - run the test over SVN trunk (make sure you actually run trunk via
   /proc/xenomai/version, should give "2.3-rc2")

 - report your findings

Again, *precisely* your problem was understood, fixed, and applied to
both branches. It should really not show up the same way as before.
