Do we have a theory on what might have caused the regression before?
Or at least something that is different this time around?

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).
That would be a good starting point to understand it better. In fact if the previous problematic patch works fine on master, then, we are sure that something in the sub-system would have fixed the issue.
I'll wait for the outcome of this experiment before re-sending my patch.
Thanks in advance Kenny for volunteering for this activity.
