It seems to me that the fix was released but in the linux package not
the alsa-driver package.

Bug description:
Listening to music (in this case via rhythmbox) results in stuttering
sound. This happens once in a while (every 1min or so) on low load and
increases when there is a lot of disk activity.
Using the driver version 2.6.32-22.201005210601 from audio-dev-ppa.
Problem does not appear with the official lucid drivers in linux-
backports-modules-alsa-lucid-generic (2.6.32.22.23). I'm using the dev
version for nvidia hdmi-support.
my alsa-info.sh output: http://www.alsa-
project.org/db/?f=b8502df177229c979aa475c0aaad0a02c2825b23
dmesg get's filled with these (not in accordance with stuttering):
