And, quite frankly, I'm not sure if users will be happy with 
the $subject patch, because it _really_ breaks things (well, 
the kexec users who don't use suspend might be, but surely 
suspend users who don't use kexec won't).

Please note that i havent reviewed the patches and i did not 
take any sides in the discussion - i just flagged the maintainer 
ping-pong. As long as we pick one of the patches (or a third 
one) within a bound amount of time we should be fine :)

I'll defer to Rafael here; he's been working the most in this area.
The changelog wasn't very complete for the original patch, but it
sounds like in the kexec case the newly booted kernel will get an igb
device in D3 which it can't handle?  That really does sound like a
driver bug, not something we should mess with in the core.
