Some more debugging (printf´s ;-)) of the example satch.c  revealed that 
taskSpawn hangs in a function of the nucleus module nucleus/pod.c called 

This is the caller stack :


and xnpod_schedule never returns.
Does anybody can give me some more hints for debugging or knows the solution 
for this problem ?

Thank you for your help in advance.
