Subject: Re: [Bug 16007] x86/pci Oops with CONFIG_SND_HDA_INTEL

I think the basic problem is that Yinghai's patch broke your system,
and this is a regression between 2.6.33 and 2.6.34.

We could use a quirk like yours (which looks fine, BTW) to cover up
this regression, but I don't like that approach because other machines
are probably affected by the same issue, and we'd have to find and
fix them one-by-one.

I think it'd be better to figure out the problem with 3e3da00c01d
and fix or revert it.  I said earlier that I wasn't in favor of just
reverting it, and I still don't like that option because it will
likely break something.  But Yinghai didn't supply any details about
the system that 3e3da00c01d fixed, so I don't know how to fix things
so both that system and yours work.

I assume that 2.6.34 with 3e3da00c01d reverted will work fine even
without "pci=use_crs".  Can you try that and attach the dmesg log?
