I debugged this a bit more and the good news for you is that spurious
IRQ messages have got nothing to do with your patch. Looks like the
spurious interrupts on interrupt line 0 were always there - just that
they were getting silently ignored earlier. I am still debugging what is
causing these spurious interrupts.
Thanks,
