Well my resolution is to run with "acpi=noirq". I'm not sure if you'd call
that a resolution but I can live with it. The main reason why I reported this
problem was in case someone else runs into it in the future.

I attached three sets of dmesg and interrupt logs to the bug tracker :
http://bugzilla.kernel.org/show_bug.cgi?id=6654
If you need more info let me know.
