omap-mcbsp 49022000.mcbsp: TX Buffer Overflow!

Hi,

I'm trying to use g_audio on my Nokia N900 with mainline kernel. Seems it does not work. No sound when I play from a laptop, and also see a lot of error like below: [ 4729.557647] omap-mcbsp 49022000.mcbsp: TX Buffer Overflow! ...

Is this a know issue?

Thanks Dave
