This is cool, but I have one major reservation about it: it will make kernel panics take a lot more screen real estate without containing more information, and we already have problems with things scrolling off way too easily.
For that reason I would like to request that this *only* enabled by an explicit command-line option or similar (disasm_oops, maybe?), so that the user has to opt-in. In other words, if *you* are debugging your own kernel, and don't expect to ship oopses off to someone else.
