Where exactly is the freeze? Are you sure the interrupt handler is being called only once? Perhaps you're not clearing the interrupt status and your handler is being called repeatedly?
It was verified with oscilloscope that interrupt handler clears the interrupt. The interrupt line goes from low to high and stays there. I have prints in interrupt handler, they appear only once. It's difficult to say where it freezes. I've tried magic sysrq on serial console, but got nothing.
