x86/pci Oops with CONFIG_SND_HDA_INTEL

From: Graham Ramsey on 19 May 2010 11:20 Hi, I am on x86_64 with latest (v2.6.34) kernel. When i set CONFIG_SND_HDA_INTEL=Y It hangs at an early stage in boot with kernel oops. When i use CONFIG_SND_HDA_INTEL=M the machine will boot, and i get the dmesg (below). I have bisected down to one commit that causes the problem: commit 3e3da00c01d050307e753fb7b3e84aefc16da0d0 x86/pci: AMD one chain system to use pci read out res ... I have reverted this in my current kernel (v3.6.34) and it seems to work OK like this. Is it possible to get this commit either removed, or amended to work with SND_HDA_INTEL ?

I CC'd Yinghai, the author of that patch. That commit went in after 2.6.33, so this is probably a regression between .33 and .34. Can you open a report at https://bugzilla.kernel.org and respond to this thread with the URL? Please attach the complete dmesg (with SND_HDA_INTEL=m) to the bugzilla. Thanks a lot for your report!
