I see a similar Problem with (simple) ogg123 (out of
pkgsrc/audio/vorbis-tools) since several days with -current userland
and kernel on my amd64 machine:

It starts up displaying some (*.ogg file) info and gets stuck
producing a whole cpu's load, but producing no audio output. The
process itself is only 'kill -9 [PID]'-able.

(pkgsrc/audio/) xmms dumps core when replaying vorbis files (mp3 still
work fine):

  $ gdb /usr/pkg/bin/xmms xmms.core 
  GNU gdb 6.5
  [...]
  Core was generated by `xmms'.
  Program terminated with signal 10, Bus error.

(pkgsrc/multimedia/) mplayer still replays vorbis files flawlessly.

I did not dig into this so far. Is there an (easy) way to check if a
(running) binary has kqueue related problems?
