This looks normal - GPIO0 is connected to an interrupt pin of the CPLD.
lubbock_init_irq function should be setting up a chained handler for the GPIO0.
And that chained handler (lubbock_irq_handler) should further decode which
IRQ bit is set. Do you see the handler being called? Can you print the (pending)
variable in the handler?

With best wishes
