I had already tested pci/next, but as luck would have it, I had pulled it a day before Bjorn Helgaas applied the series. I can't imagine this is a linux-stable candidate though, as it appears to be a bit more of a "new feature" thing. I'm still stuck wondering how this showed up as a regression for me. Brian
