With runtime PM, if the ethernet cable is disconnected, the device is transitioned to D3 state to conserve energy. If the system is shutdown in this state, any register accesses in rtl_shutdown are dropped on the floor. As the device was programmed by .runtime_suspend() to wake on link changes, it is thus brought back up as soon as the link recovers. Resuming every suspended device through the driver core would slow things down and it is not clear how many devices really need it now. Original report and D0 transition patch by Sameer Nanda. Patch has been changed to comply with advices by Rafael J. Wysocki and the PM folks.
