dmesg log booting 2.6.34 without pci=noacpi
I have a Thinkpad r51e and starting with this commit (which is necessary for my
gpu to work see bug 15626), my audio no longer works unless I boot with
pci=noacpi:
commit c414a117c6094c3f86b533f97beaf45ef9075f03
Author: Alex Deucher <alexdeucher at gmail.com>
Date: Tue Mar 30 17:22:32 2010 -0400
drm/radeon/kms: disable MSI on IGP chips
Doesn't seem to work reliably and the pci quirks don't
always work.

If I boot with pci=noacpi, the audio works at first, but it usually stops
working after running a few programs that use sound. When the audio stops
working, this message appears in my dmesg log:
ALSA sound/pci/atiixp.c:690: atiixp: XRUN detected (DMA 0)
