Yinghai's changes would probably be in v3.15 or later. Can you open a kernel.org bugzilla report and attach complete dmesg logs of the working and broken kernels to it? There might be more useful resource-related messages from the PCI core. I wouldn't start bisecting yet, but if you're in the mood, this commit: 96702be56037 "Merge branch 'pci/resource' into next" looks like a good place to start, so you could try the pre-merge commit: 04f982beb900 "Merge branch 'pci/msi' into next". If 04f982beb900 is good, there are only about 15 commits on the pci/resource branch to look at. Thanks for the report!
