Christopher, Sorry, I should have been more clear in my previous comment. There was no checkbox for third party drivers, but I did select a checkbox for installing third party software, and that apparently also includes third party drivers (although the user has no way of knowing this).
I had a spare external USB drive so I tested this out with Ubuntu 14.10. I installed once without that checkbox unselected: the 'wl' driver did not install and everything worked perfectly. Then I reinstalled with it selected: The 'wl' driver installed and I got the same problems (installation froze, reboot froze, stack trace in dmesg). I had to use the workaround I specified in comment #8. The official Ubuntu installation instructions even advises selecting it and says "We advise you to select Download updates while installing and Install this third-party software now" ( http://www.ubuntu.com/download/desktop/install-ubuntu-desktop ) . So although it is not installed by default, it is still too easy to install this driver which causes problems on unsupported broadcom devices. -- 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: Incomplete 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.
