As Joe said on 2.6.x based systems it is enough to use "jackd" instead
of "jackstart" (jackstart will complain but will work anyway). Another
piece you need for that particular kernel is to have the realtime lsm
kernel module loaded but that is activated as part of the normal install
if you use the planetccrma-core-* meta packages.

Hmmm, looks like jack is hanging (and its watchdog process is killing
it)... what soundcard do you have installed?
