I can understand your frustration. :)

But its interesting it sort of worked, no?  The bit you discovered 
earlier with the dump_stack debugging call, where we're actually 
disabling the irq twice was interesting.

If you use the debugging patch with this change, does it show any 
different in logic between the working cases and the instant-reboot case?
