Actually, no, it is not. It happens to be almost okay for s2ram, but it will mean no messages for suspend to disk... and that is bad. Console subsystem should be stopped when console device is stopped, and restarted when console device is restarted. If that is not practical, it should be stopped when all the other devices are stopped, and resumed when all the other devices are resumed. Currently, pm_restore_console is not called when devices are resumed before writing to disk (in s2disk case). pm_prepare/restore_console would need to be split to two function to DTRT with s2disk.
