I was using jackd (0.100.0-4) before I gave up and bought a M-Audio
FireWire Solo, which was yesterday.  One complicated situation
abandoned...on to another.

I'm now building jackd 0.101.0, which has the freebob support I'll need
to get the FireWire Solo going.  Once I get the newer jackd rolling I
plan to give the us-122 another try.  I googled like hell on the us-122
problems (choppy audio), and found a few others who also experienced it.
It wasn't an overrun problem; I was running jack with few xruns with
settings similar to yours.  I read about a amd dual core timing bug that
was fixed (at some point) in jack.  Perhaps that was my issue.
