The reason I knew for this problem was if handle_edge_irq was used for
some interrupts. But problems of this kind for IMX GPIOs are fixed in
1.3-03.

Do you have this problem with in-kernel or out-of-tree drivers? With
real-time or non real-time interrupts? Could you show us
/proc/interrupts before the system freezes?
