There is no more problem (sorry for omitting advice).
It was not related to Xenomai. The problem was with the I/O card.
rt_intr_* calls were not sufficient. I had to make I/O card API calls too.
Something like this:
while (!end)
{
rt_intr_wait();
// disable interrupts
rt_intr_disable();
InterruptEnable(board, FALSE); <-------------- this call was not there
when the problem was
processing...
// reenable interrupts
rt_intr_enable();
InterruptEnable(board, TRUE);
}
Thanks
Hubert

A stupid advice: did you check rt_intr_wait return value ? Maybe
something is badly configured and rt_intr_wait returns an error 50000
times ?
