** Description changed: - Steps to reproduce: + The bcmwl driver is causing kernel panics throughout the system running + the3.8 kernel. The panic can be reproduced in multiple ways, including: - 1. Begin Ubuntu user session with Unity - 2. Open Terminal and run: sudo iwconfig + 1. Running "sudo iwconfig" (every time) + 2. Resuming from suspend (occasionally) + 3. Trying to report a bug from apportcheckresume - 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). + The resuming from suspend case appears to be related to a wpa_supplicant + error, where the kernel complains that wpa_ctrl_open is not a command. + 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). 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 + 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 + [ 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.
