I can confirm that installing bcmwl 6.30.223.30+bdcom-
0ubuntu2~eugenesan~raring1 from
https://launchpad.net/~eugenesan/+archive/ppa has solved the "kernel
panic when running sudo iwconfig" issue for me on Ubuntu 13.04 (Raring)
with BCM4313 wireless card on Dell Vostro 1540.

Title:
  Update to 6.30.x driver needed to avoid kernel panics on some cards

Status in “bcmwl” package in Ubuntu:
  Confirmed

Bug description:
  The bcmwl driver is causing kernel panics throughout the system
  running the 3.8 kernel. The panic can be reproduced in multiple ways,
  including:

  1. Running "sudo iwconfig" (every time)
  2. Resuming from suspend (occasionally)
  3. Trying to report a bug from apportcheckresume

  Each kernel panic looks exactly like the one I have attached. In every
  case, Xorg stops responding (in the resume case, the laptop gets stuck
  on a black screen with a command line cursor) and the machine must be
  forcibly powered off.

  Connecting to networks works perfectly fine, at both 802.11g and n
  speeds. If none of the above commands are invoked, the driver operates
  the network card without an issue.

  My laptop has the BCM4331 wireless card and it's being managed by the
  wl driver. When running sudo iwconfig, I was connected to an auto-mode
  802.11b/g/n router (I believe I was connected via wireless-N because
  the link speed shown was 144 Mbps).

  A functional version of the bcmwl driver can be found in this PPA:
  https://launchpad.net/~eugenesan/+archive/ppa To resolve this bug,
  bcmwl-kernel-source in the official repositories for Raring needs to
  be updated to 6.30.

  bcmwl-kernel-source version 6.20.155.1+bdcom-0ubuntu6
  network-manager version 0.9.7.995+git201301311547.17123fc-0ubuntu1
