Ok, thanks for the investigation - perhaps that write call is not considered a blocking call, or not so on RT kernels, or it gets stuck in the for (;;) loop around the write call in pa_fdsem_post - might be worth checking the result from that write call to see what goes wrong?

Happy bug hunting :-)
