The stack dump isn't really necessary ... Does anyone else think we
should turn it off by default?

I tend to look it up by hand -- 102a4990 is the most interesting address,
(IAOQ) and r2 is sometimes also interesting (not in this case, it

It'd also be helpful to show where the kernel got to before it did the
stack dump -- might help track it down.
