If you'd like, I could try re-applying the previous problem commit or your
attempted fix on top of Linus' master if you'd like to see if something was
fixed somewhere else in the PCIe subsystem, but if you think it's not worth-
while I'm satisfied with the current fix (or probably more-exactly for my
particular machine, lack of regression).
