Maybe the documentation is not clear enough, but you have to make the changes to multiplexed GPIO irq handlers, otherwise all hell will break loose when such an irq will happen, even in the absence of real-time drivers. Also, if your processor is an armv4 or armv5, you should consider enabling the FCSE. -- Gilles.
