Hello, after hours of searching, I have finally found the problem. It was a bug in my "SimpleRPC" library. The thread function, responsible for the "lockup", mainly constists of an endless loop ( while(pObj->nRun) ) that polls a request queue. This was not a problem as long as this thread was a standard pthread. Turning this thread into a real-time task by adding a call to rt_task_shadow at the beginning of the thread function (before the while loop) resulted in a frozen linux system.
I used to work with the following system Gentoo Linux Linux Kernel 2.6.17 (IPIPE 1.4) Xenomai 2.2.3 Now that I know, that upgrading to Xenomai 2.3.0 is not a problem, I plan to upgrade to the 2.3.x branch.
