I have done that, but it doesn't help in making testsuite pass.

I have tried to debug things a little, and found the problem is in the 
rt_make_hard_realtime call.

If I comment the call to this function, in latency.c for example, the 
test seems to run (with overruns though):

If I let the rt_make_hard_realtime call, the program is blocked in this 
call and never continue to the next line (rt_task_make_periodic call).

Any idea ?

	Cheers,
