The problem is in M_NOWAIT flag for the kmallocs in feed_rate_init(). We can
wait at that point and my system has been running with this patch for almost a
week and still sound functioned normally.

This fixes my sound problem on my laptop.

Thanks!

I have committed the patch plus I have gone through every single
    kmalloc in /usr/src/sys/dev/sound and fixed the M_NOWAITs -> M_WAITOKs.
