>From looking at wl_linux.c, it seems to be loading the driver for any Broadcom device containing the PCI device ID 0x43##. This is incorrect.
In my opinion, this driver should not be installed, or at least not be loaded, by default in Ubuntu. If someone would like, they can look at the existing source code and the README file included with the wl driver and can create a patch to do further validation of the PCI ID. Broadcom is unresponsive to me on this. At this point, the workaround is as follows: 1. During installation, run "sudo killall -9 modprobe" when installation seems to freeze up to resume it. A hard reboot may be required after installation completes. 2. After booting into Ubuntu, add "blacklist wl" to the end of "/etc/modprobe.d/blacklist.conf". Again, a hard reboot may be required. 3. After this everything should be working as normal. If you need to load the b43 module by default, you may need to add "b43" to "/etc/modules". -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to bcmwl in Ubuntu. https://bugs.launchpad.net/bugs/1313221 Title: modprobe wl crashes with broadcom 4306 Status in “bcmwl” package in Ubuntu: Confirmed Bug description: I was installing Xubuntu 14.04. It said 'Configuring bcmwl-kernel- source (amd64)' and in the details "DKMS: install completed." and it just froze there. To continue installation I had to open up a terminal and execute 'sudo killall -9 modprobe' After getting it installed, I found out that the 'wl' module causes problems with my broadcom 4306 wireless card. I had to add it to the module blacklist. When I load the 'b43' module first (which is the correct module for my card), it loads fine [dmesg-b43-first.txt, 134-136]. Then when I try to load the 'wl' module after that, it seems to fail gracefully [dmesg-b43-first.txt, 203-end]. This seems normal to me. However, when I load the 'wl' module first, I get a stack trace [dmesg-wl-first.txt, 62-end]. I cannot unload it after that as it says it's in use. If I try to load 'b43' after that, modprobe just freezes (which I assume is what happened during installation). The system also freezes during reboot and I need to hard reboot my system. Two issues here it seems: 1. The wrong module is being automatically loaded for my card. It should be 'b43' not 'wl'. 2. More importantly, 'wl' is causing a stack trace and causing the modprobe process to lock up when loading 'b43'. Please let me know if you need any more information and thank you for the assistance.
