Christopher,

Sorry, I can't help you out with the bisect right now as I need my
laptop for a sprint  (I'm leaving in a couple of hours).   I've just
done a fresh install of Trusty and brought it up to date  - the bug
nolonger manifests itself.  I had previously tested with kernels that
had previously been known to work and the problem persisted, but a clean
Trusty install is working perfectly with 3.13.0-24-generic, so I suspect
that one of the recent changes I made on my machine would have
introduced this problem.    When I get back from the sprint I will re-
apply some of my recent setup changes and see if I can reproduce the
error.

Title:
  kernel panic when intel wireless card associates

Status in “linux” package in Ubuntu:
  Confirmed

Bug description:
  Since this morning, following an update, my machine kernel panics as
  soon as NetworkManager connects the wifi, or if I press the key to
  power off the wifi card.

  Blacklisting the wifi modules (iwlwifi and iwldvn) and using a USB
  wifi card instead results in a stable system.

  I'm on a Lenovo Thinkpad Edge E130, running Trusty, running 3.13.0-24-generic, and the intel card is, according to lspci, an Intel Corporation Centrino Wireless-N 2230 (rev c4).
