So I have made that mistake before, and never learn.  But the good thing
about that is that it now rang a bell.  I once had suspend issues with a
completely different Intel device on another Lenovo laptop, which turned
out to be caused by the Lenovo firmware accessing the device while it is
in D3: https://lkml.org/lkml/2015/3/2/183

I don't have a clue about how these things work so this might be
completely unrelated.  Just thought I'd mention it as an example of how
the Lenovo firmware can do unexpected things.

>From the reports so far, it looks like the issue at hand affects most
(all?)  Lenovo Thinkpads with an e1000e part.  If you haven't tried
already, it might be interesting to see if you can reproduce it on a
Thinkpad.
