IAOQ head provides the location of interruption. It was a instruction memory protection fault. Since this is a kernel address, this likely indicates the page tables weren't setup correctly, or the instruction cache wasn't flushed correctly.
I'm thinking it would help to localize the change that introduced the interruption.
