Fwd: pcm says `channel dead' with snd_hda

[Zhihao Yuan]

I asked this question on freebsd-stable, but they tell me to ask this here.
Here is the original mail. Recently, I updated my kernel & world. And I
found that this problem becomes worse -- my /var/log/message was filled up
with something like

Dec 14 08:13:16 compaq kernel: pcm0: chn_write(): pcm0:virtual:dsp0.vp0:
play interrupt timeout, channel dead

It's really a problem now.

~> uname -a FreeBSD compaq.yuetime 8.2-PRERELEASE FreeBSD 8.2-PRERELEASE #8:
Thu Nov 25 15:48:19 CST 2010

amd64

Sometimes, pcm prints the following message to the console & dmesg.
pcm0: chn_write(): pcm0:virtual:dsp0.vp0: play interrupt timeout, channel
dead

What's wrong? I haven't seen this in 8.1-RELEASE or other version before.
One post said that such message comes with noise, but I'm not sure. I uses
mplayer, sometimes quodlibet (gstreamer backend).
