I just did a re-cvsup this morning, and this is the first time in a
long while that I've noticed the problems were fixed.  How long ago
did you build your kernel?

Note:  now I'm seeing messages like this:

Aug  9 12:13:56  /kernel: pcm0: hwptr went backwards 2144 -> 1132
Aug  9 12:13:57  /kernel: pcm0: hwptr went backwards 72 -> 3332
Aug  9 15:33:36  /kernel: pcm0: hwptr went backwards 172 -> 24
Aug  9 15:34:13  /kernel: pcm0: hwptr went backwards 100 -> 3820
Aug  9 15:35:27  /kernel: pcm0: hwptr went backwards 212 -> 28
Aug  9 15:35:28  /kernel: pcm0: hwptr went backwards 184 -> 3288
Aug  9 15:35:28  /kernel: pcm0: hwptr went backwards 2240 -> 2196
Aug  9 15:42:16  /kernel: pcm0: hwptr went backwards 2116 -> 1140
Aug  9 15:43:41  /kernel: pcm0: hwptr went backwards 184 -> 20

But, maybe these debugging messages were recently added to channel.c. 
I know the problem was in channel.c.  Otherwise, mp3's play OK now.
