I also find the CONFIG_PM approach not terribly reliable... too timing sensitive, and it forces boards to add CONFIG_PM which is not necessarily the nicest thing to do in embedded space. Sounds better to me to clean up the initial patch to ensure it's not going to introduce bloat for other platforms and use that, ie just consider it as yet another HW errata. Cheers, Ben.
