Cyclone V - Interrupt Handling

Have there been any updates to your FPGAINT driver? It seems as though whenever I get a valid interrupt, the fgpaint_irq_handler gets repeatedly called and locks up my system. (I end up in an infinite loop with the "FPGA interrupt module: fpgaint_irq_handler called" output message on the console.) I am not a driver guru by any means but is your driver an edge or level triggered ISR? Also, it appears that the fpgaint_irq_handler process calls wake_up_interruptable(); Can you offer any assistance in understanding the connection between that call and my "user space" ISR?
