Like I said I have been frustrated with jack and pd crashes, especially during a show, sorry that happened to you. I think though it is settling down again in 11, that whole pulseaudio stuff made things overly complicated for no reason. I have had issues with ffado & alsa, sometimes jack fires right up, sometimes I have to run it from command line first. I can never tell, but once it's up and running I no touch.
