Public bug reported: Steps to reproduce:
1. Begin Ubuntu user session with Unity 2. Open Terminal and run: sudo iwconfig After doing this, the end result varies--either the entire screen is replaced by a terminal window showing the kernel error, or the Unity session appears to continue but all running windows stop responding and the computer cannot be restarted from Unity (need to use power button on laptop). 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). 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.
