Same problem here, on a Dell Latitude C840 with a clean install of Ubuntu 12.04.2. I can try to install from the CD or start the installer from the LiveCD, there is always this kernel bug thrown, and the system hangs.
The laptop is connected only to the LAN, but WiFi hardware is present. I'd love to post more, but since it happens during install, I have no way of catching the full error screen. The first line reads: kernel BUG at /include/net/cfg80211.h:2351! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1018547 Title: Kernel panics when connected to wifi To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1018547/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
