Hi all,
using the latest SVN version of Xenomai and the integrated patches on a 2.6.19
kernel
I get a kernel Oops with my application and the system freezes.
Here is the oops:

Unfortunately I have no idea, what causes this oops.
Is there anybody that has some hints on this oops?
Thanks in advance.
Regards
Mathias
