Very likely, the current linux clockevent is not the one supported by
Xenomai. cat /proc/timer_list will tell you which driver is used for
clock events.

The one supoprted by Xenomai is the one called:
"gp timer"

If it is not the one you have, then you have to disabled the
configuration option corresponding to the timer used.
