I suspected that during resume from hibernation the boot kernel (the one that loaded the image) did something to hardware and the restored kernel didn't handle that change properly. It is hard do say what piece of hardware that was, however (it might or might not be the NIC, it may be pure coincidence that the NMI messages appear in the log at this point).
