jackd crashed using freebob cannot complete execution of processing graph ... zombified

using the jackd in hardy via my hp compaq v6000au laptop with mini firewire port I get all this processing graph crap and then jack crashes but firewire connection remains active and requires reset or a power OFF/ON. I have a presonus firepod (FP10) which with previous versions of jackd and freebob worked, maybe not perfectly, but this is a serious step backwards. there are also reports on the ubuntu forums of this happening to people with M-Audio cards also. could this be a cable problem? or a problem with getting realtime priority? I have taken all the necessary steps to ensure realtime priority.
