Hello gna org,

When porting and running a vrtx-task ("tercas" working fine in VRTX) to the xenomai-linux environment I always got the below kernel Oops creating/starting the thread.
I use Kernel: 2.6.28.7 and xenomai: 2.4.7. 
If I run other examples like "native/trivial-periodic" this is working fine.

Please, could someone look at this /var/log/messages log and see why this is not working:
Thank you, 
Hans
