I started downstream:
  https://bugs.debian.org/1010365

did some more debugging and moved upstream (the link is mentioned in
each commit message) roughly 10 days ago:
  https://bugzilla.kernel.org/show_bug.cgi?id=215925

As I wrote in response to Thorsten Leemhuis (regressions@), who looped
in a bunch of people:

   I had spent so much time bisecting that issue that I concentrated on
   trying to summarize it properly in Bugzilla, failing to check
   reporting guidelines and best practices (I even missed the
   Regression: yes flag in my initial submission).

Again, sorry for failing to notify everyone in the first place, I tried
to have the contents of the report squared away.

That being said, as mentioned on regressions@ & linux-pci@, I'm happy to
test any attempts at fixing the issue, instead of a full-on revert. I'll
also try to track mainline more closely, so that such obvious issues
don't go unnoticed for ~1.5 release cycles.


Cheers,
