Assembly code switches to the special interrupt handling stack prior to calling do_IRQ(), so I can't see how you would ever find yourself on the process stack in stack_overflow_check(). Jan The point of the code is to sample the original process stack and check if the code there is a stack pig, not the interrupt. I'm not sure it would be worth adding a special check for irqstack/exception stacks because nesting there should be pretty rare.
