Thank you Gilles, this was may case, disabling a C1E power state in a
BIOS definitively solved my problem.

Gilles.
If you find useful please add bellow text to the TROUBLESHOOTING.adoc
file.
On AMD x86_64
^^^^^^^^^^^^^
You will most likely also see the following message:
--------------------------------------------
I-pipe: cannot use LAPIC as a tick device
I-pipe: disable C1E power state in your BIOS
--------------------------------------------
Xenomai sends this message if C1E option is enabled in a BIOS. To fix
this issue please disable C1E support in the BIOS. In some Award BIOS
this option is located in the +Advanced BIOS Features->+ menu (+AMD
C1E Support+).
On some systems, above message may not appear in the system log.
IMPORTANT: Disabling +AMD K8 Cool&Quiet+ option in a BIOS does not
solve the problem.
