Problem with MPC8536 and external IRQs when using a loadable kernel module

2010-12-09 Thread Mark Pearson
I have a curious problem. This is on a MPC8636 based platform with 36-bit address space (that may or may not be important). I have a very simple driver that registers for one of the external IRQs with a trivial interrupt handler. It works great when built in as part of the kernel. However,
