In my case I need to load some another kernel device module(the one that resumes correctly ...) otherwise devices without driver attached would not be put back into D3 state. eg, in my case I unload snd_hda and load it again _before_ suspend. With "pciconf -lvc" you can inspect device power states. -- Paul
