Ok, I hope this helps a little bit more :) . Did you try a possibility when your interrupt handling function always returned IRQ_HANDLED? Also, did you have a look at the source code of these kernel functions ( http://lxr.linux.no) - __do_IRQ(), handle_IRQ_event(), note_interrupt(), __report_bad_irq and misrouted_irq()  ?

I think that the __report_bad_irq() function is what produces the "nobody cared" message and the note_interrupt() function is what
prints the "Disabling IRQ" message.

Just in case you would be looking for the term "spurious interrupt" -
