As a side note, having to revert that patch to get your system up and
running is a reliable indication that something is wrong with your
interrupt mapping, and that you are using 0 as a valid interrupt number
(which has been declared invalid a long time ago by the chief penguin).

Hopefully Gregory has put you in the right direction.
