Happy new year to all!

Back in the office, I tried out the patches from Chilles and Philippe.
And yes, it is working now! No crash!
Using these patches, I can now call a system() call out of a rea ltime task=
 that is followed=20
by a rt_task_sleep() and a printf() without crash on a 2.6.19 kernel.

Thanks for the support!

Best regards
