Yes, a printf() directly after the system() fixes the issue.

I have added a hacky trace mechanism in the kernel to see what's happening
(whenever the nmi_watchdog with the kernel oops appears).
What I can see is that rt_task_sleep(); is completely passed.
If I modify my application to add a second rt_task_sleep() directly after the
existing one, I see the both rt_task_sleep() calls are passed.
The freeze seems to happen with the printf() call after the rt_task_sleep.
Unfortunately, I do not know where I can trace here...

Best regards

Mathias
