>From FFADO maintainer:

   Bug: Segfault in ffado-test-streaming, seemingly while shutting down.
        This may be due to the user stopping the program or an xrun.  More
        details about the scenario are required.

   Suggestion:
       Test using jackd rather than ffado-test-streaming.  The
       ffado-test-streaming tool does not receive extensive testing and
       exists mainly for the use of the development team.  It would be 
       interesting to know why the user was running ffado-test-streaming.

       If FFADO still fails when used with jackd, run
           jackd -d firewire -p512 -n3 -v6 >& /tmp/ffado.log
       and post the result to the ffado-devel mailing list for further
       follow up.  Include the output of ffado-diag if possible and mention
       which audio device is in use.
