If a tasks switches to secondary mode it would act like a normal Linux thread. I haven't used Xenomai 2.6 in a while but if you are seeing both tasks drop to secondary mode you may want to list the resources that they are sharing and how you are sharing them and then we can see if something would cause mode switches. Are you seeing both threads drop to secondary mode?
