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:/
bcmwl-kernel-source version 6.20.155.
network-manager version 0.9.7.995+
