I thought of one more thing you might want to add: device_pm_add() doesn't handle the case where dev->parent is NULL. You could put in that static "all_devices_sleeping" flag, which gets set at the end of dpm_suspend() and cleared at the start of dpm_resume(). > Okay, I also have the appended patch on top of this one. :-) > > Rafael > > --- > From: Rafael J.
