Hahah, you're so in luck: I just sent this mail and hibernated my laptop
and got the same BUG. What's the chance of that happening?! Apparently
big enough.

But I was able to catch the warning before it too. So the question is,
do you have an e1000e eth controller in that machine too?

Because the symptoms below are consistent with the observed behavior:
e1000e fails to initialize MSI interrupts for whatever reason and falls
back to legacy interrupts.

Then, PCI core shuts down and BUGs because the msi_list is empty.

Anyway, lemme add e1000e people too to the fun thread.
