and .text.lock.pcm.oss ... you seem to have the same problem as Diego.

Well. The emphasis is on "might". That locking bug was on an error path
and it's quite possible that the deadlock is due to a different bug which
is still there.

Now seems I can't get them stuck.
Hmm, Before I just opened twice /dev/dsp IIRC and then both processes got
stuck in D.
so snd_pcm_open_file must have returned < 0
I can try to play a little with it tomorrow to see why gets into the error
path.

O_NONBLOCK usage when snd_pcm_open_file() returns -EAGAIN (e.g.
SUBSTREAM_BUSY() is true, i.e. substream->file != NULL) is a trivial
way to get into the error path.
