urndis panic

[Patrick Welche <prlw1%cam.ac.uk@localhost>]

I just plugged someone's mobile phone into a 9.99.7/amd64 laptop, which
made things freeze. I then unplugged it, and then the laptop rebooted.
(Not sure if the unplugging part is relevant.) I have a nice core file
though:

(I'm unlikely to do that again, but can probably get hold of the phone again
if useful.)
