To me the proper approach would be to split it so that - early_resume() restores power & config space etc... so that existing devices can move on (might check for removal). There's no other hotplug activity - normal resume() restarts handling of events such as insertions Now, while I do have some cardbus & pcmcia stuff somewhere, I also don't have much time to hack on this right now...
