Hi Leif, Please see FX's excellent coverage on this issue. Sure, I could/should post what version I'm working on, but this is private, personal research, hence the vaugue description. Plus, I _know_ there are plenty of folks out there _much_ smarter than myself on this kind of research, so I'm just posting a "Hey, I'm seeing this, anyone else?" Folks, give "debug kernel" a try like FX mentioned and see what happens. It worked with "debug k" on my version I'm working on, but that's a Cisco question I guess.

Hi All, At level 15 permissions, when I enter "debug k" on the CLI the router freezes immediately, requiring a manual reboot. While not a vulnerability per se, perhaps something to keep in mind from the fat-finger risk? Anyone else seeing this?
