Could you re-iterate (again) your configuration? There are other
"disable_irq()"s in the tree, and it sounds like the new one is just
_completely_ broken on your hardware - there must be something bad
happening wrt the IO-APIC, and I'm sure Ingo will find it now that it
apparently is fairly easy to trigger.

One thing you could try is to just make [en|dis]able_ioapic_irq() be
no-ops, and also send me the output of

grep '=y' .config

(for example, some of the mouse drivers use disable_irq(), and I wouldn't
notice because I have a serial mouse etc etc)
