Hi Gilles,
The kernel is booting and I executed latency and xeno-test commands. The results are below.
linaro@linaro-alip:/usr/xenomai/bin$ sudo ./latency
== Sampling period: 1000 us
== Test mode: periodic user-mode task
== All results in microseconds
warming up...

Ok, you are the second to report this issue, so the patch must
be touching bits it should not touch. Please try that one instead:
