There is no more problem (sorry for omitting advice).

It was not related to Xenomai. The problem was with the I/O card.=20

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);
}=20


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 ?
