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
    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)

Did you try 2.6.35?

Comment 4 Tom Stellard 2010-09-14 07:04:14 UTC

This is still an issue in 2.6.35.

Comment 5 Alan 2012-06-14 17:26:32 UTC

Is this still present in  modern kernels ?
