I am also having a MPC5200 based board running Wolfgang's kernel 2.4.25.

I am already using DMA for IDE and FEC so Audio would be my third DMA task. I remember that it used to be difficult to get more than two tasks running at the same time. Would you send me or post your bestcomm sources since I'm not that proficient in kernel programming. Thanks Stefan
