Yes, Iam aware of this, but in fact the waiting via pause or sleep in 
the Linux process (main function)
failed and results in a system lock up.

The trick of calling rt_task_join instead of doing a pause is a nice 
idea, but it doesn't solve my problem fully(see below*).

It is not my concern to call a standard linux function in the RT task.

*The reason of my request was to figure out why any of the standard 
linux functions
(e.g. pause, sleep,..., whether called from the linux or RT task) 
results in a system lock up and why the  functions rt_task_wait and
rt_task_sleep, for example, produce the error behaviour described in the 
first mail.

So I think of an timer issue, or a wrong xenomai configuration or 
something like this, but can't really
figure out the problem...

Iam running Xenomai version 2.2 and Kernel 2.6.15 on a kanotix system.
