Ok, I installed 8.04.1 and reconfigured everything.  Here's the output of jackd from 
the command line:

If I run qjackctl I get the same output plus hundreds of lines of:

"cannot complete execution of the processing graph (Resource temporarily unavailable)"

Perhaps I need to tune my jackd config?  Before I submit a bug report please let me 
know if there's any more info you would like or any other tests I could perform. TIA!
