False positive of the test: only the -n mode is supported over Xenomai, which is unfortunately not default. The default mode seems to cause a busy loop in cyclictest, effectively locking up the box (the Xenomai watchdog would have detected this). Anyway, the test needs fixing to avoid misunderstandings.
