- your hardware is broken and is generating spurious interrupts (a

peripheral which deasserts its interrupt output before its interrupt

handler has been executed will cause spurious interrupts).

That is what got me. I forgot to loop back the interrupt request bit to hold the irq state until the interrupt service routine could clear it.

assign irq = (irq & ~irq_clear) | (irq_trigger);
