Re: pcm status
This is directly traceable to entropy harvesting by /dev/*random. I know it's not an option if you need to use ssh, but not loading random.ko will fix the sound problems when moving the mouse or typing. It doesn't fix the 'hwptr went backwards' messages, though.

Re: pcm status
If it helps at all, it's marginal. I still get skips. On Sat, Jan 20, 2001 at 05:36:08PM +0200, Mark Murray wrote: This is directly traceable to entropy harvesting by /dev/*random.

Re: pcm status
OK, please try this, then; change the HARVEST_RING_SIZE in sys/dev/random/yarrow.h to a smaller power-of-2 (256 or 128 would be good), and let me know how that helps-or-not. Thanks!
