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.

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 ProblemType: Bug DistroRelease: Ubuntu 13.04 Package: linux-image-3.8.0-6-generic 3.8.0-6.11 ProcVersionSignature: Ubuntu 3.8.0-6.11-generic 3.8.0-rc7 Uname: Linux 3.8.0-6-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.8-0ubuntu4 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: polarimetric 2236 F.... pulseaudio CurrentDmesg: [ 25.228391] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [ 25.228863] IPv6: ADDRCONF(NETDEV_UP): eth0: link is not ready [ 25.354790] init: plymouth-stop pre-start process (1501) terminated with status 1 Date: Wed Feb 13 13:13:01 2013 HibernationDevice: RESUME=UUID=e6de4934-3dd3-42fc-954f-60d2f553fbb7 InstallationDate: Installed on 2013-02-09 (4 days ago) InstallationMedia: Ubuntu 13.04 "Raring Ringtail" - Alpha amd64+mac (20130208) MachineType: Apple Inc.
