    Just a wild guess but you probably have jackd set up to run with 'real time'
    priority. In order to do that you'll need to install a real-time kernel
    first and then boot with that kernel. Otherwise change your jackd
    configuration to NOT use real-time capabilities.... Also, you may need to
    edit other variables as well...
