Ok, so how about this? Daniel, is it enough to make the problem appear on your system (by building this into the kernel and booting with dummy-irq.irq=16)?

From: Jiri Kosina jkosina@suse.cz Subject: [PATCH] dummy-irq: introduce a dummy IRQ handler driver
This module accepts a single 'irq' parameter, which it should register for.
Its sole purpose is to help with debugging of IRQ sharing problems, by force-enabling IRQ that would otherwise be disabled.

Yes, I'll take it, give me a few days to catch up with my pending queue, don't worry, it's not lost.
