.. but there really is some semantic issue going on here. I'm not the only one for whom suspend/resume simply does not work with MCE enabled, and that "not work" coincides with the switch-over from sysdev to struct device.
I suspect it is some subtle difference in sysdev_unregister() vs device_unregister(). The message change is just a symptom of the fact that we go through different paths.
For me MCE hangs only on the *second* suspend, but it sounds like others see it on the first one.
