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:

drm/radeon/kms: disable MSI on IGP chips
Doesn't seem to work reliably and the pci quirks don't

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)

Did you try 2.6.35?
This is still an issue in 2.6.35.
Is this still present in modern kernels ?
