When I try to start jackd on both 2.6.21 and 2.6.22-rc4 compiled with
LSM support, I get the following:

ALSA: final selected sample format for capture: 16bit little-endian
ALSA: use 2 periods for capture

ALSA: use 2 periods for playback
and then it hangs.
Running the same from strace showed a hang at the following place:
