Syslink_setup() hanging at Notify_setup in Ipc_setup()

I'm trying to debug an OMAPL138 ARM/DSP interface using the latest syslink running in the arago kernel.

The linux app hangs an syslink_setup/ipc_setup()/notify_setup()/NotifyDrvUsr_open (TRUE) at:

                    /* Create the pthread */
#ifdef LINUX_THREAD
                    pthread_create (&NotifyDrv_workerThread,
                                    NULL,
                                    (Ptr) _NotifyDrvUsr_eventWorker,
                                    getpid());
#else
                    pthread_create (&NotifyDrv_workerThread,
                                    NULL,
                                    (Ptr) _NotifyDrvUsr_eventWorker,
                                    NULL);
#endif

where the code block LINUX_THREAD is grayed out (odd?)...

I compiled syslink using the defaults NOTIFYDRIVERSHM and TRANSPORTSHM...

Anyone have an idea whats causing this?
