[PlanetCCRMA] jackstart and freqtweak hang my system

[jfm3]

Granted, I'm running a kernel I built myself, so I'm really on my own
here, but when I run jackstart it doesn't start the first time:

bash> jackstart -R -d alsa -d hw
jackd 0.51.0

When I run it again, it works, but then when I run freqtweak, it
crashes. Anyone seen this or am I hosed?
