Hello Roman

I'm interested in your code also though I haven't had a chance to look 
at it yet. I am also having a MPC5200 based board running Wolfgang's 
kernel 2.4.25.

What I am wondering is, how many DMA tasks do you run besides Audio?
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
