That's entirely possible. However, have you verified that if an > async thread does a synchronization, it doesn't deadlock? an async thread can synchronize on its own cookie. so yes if we make this a global serialize, we can't do irq autoprobing in async context. If we can use PNP/etc for serial.. I don't think that's a big deal.. nobody with sane hw would need to autoprobe ever. -- Arjan van de Ven Intel Open Source Technology Centre For development, discussion and tips for power savings, visit http://www.lesswatts.org | ||||||||||||
