  I noticed the dma code has been changed from what I have.

  Also noticed that the beagleboard is getting DMA interrupts when I
"aplay":

cat /proc/interrupts | grep DMA

 12:       4646        INTC  DMA   

  but I'm not.  As I mentioned, I'm at "2.6.29-rc3-omap1", anyone
think there is a problem with pcm DMA's in that version?

  Thanks

  Rick
