[Xenomai-core] rtdm_dev_register oops

hi, i got a exception in rtdm_dev_register(). I didnt call rtdm_dev_unregister in my driver and after insmodding the module again I got a oops. xenomai 2.5.3, linux 2.6.32.11, x86 32bit, ubuntu 10.04. Attached is the dmesg-trace and a small rtdm-module foo.c for reproduction: insmod
