RTAI is in nanoseconds as Xenomai used to be in early days, but its
results are as broken as Xenomai's (watch out for the maximum!).

You likely have a SMI problem, see TROUBLESHOOTING for details.
This makes me wonder if some simple test ("dmesg | grep
CONFIG_XENO_HW_SMI_WORKAROUND") in latency or at least in xeno_test to
detect this may make this FAQ less frequent... :)
