pcm0:play:0: play interrupt timeout, channel dead

Hello,

I'm using FreeBSD 5.2.1 RELEASE.

I'm used to listening the radio on Internet using RealPlayer8, but
it always dies after a certain time running, it might be 10 or 15 minutes,
and I can see the message of the mail's subject
"pcm0:play:0: play interrupt timeout, channel dead"

What's the problem ?

I think I don't have this problem if I boot in "Safe mode", though
I've been watching what the "Safe mode" does, and it doesn't
seem to me that the "Safe mode" could affect this problem in any way...

I append my DMESG output if it can help.

Thank you.
