Title:
  wl kernel module on BCM4313 causes kernel taint on boot

Status in “bcmwl” package in Ubuntu:
  New

Bug description:
  Lenovo ideapad with BCM4313, upgrade to 13.04
  12.10 used drivers bcma, brcmsmac
  13.04 chooses kernel module wl, package bcmwl-kernel-source, 6.20.155.1+bdcom-0ubuntu2

  This causes exception on boot
  Therefore network fails to launch
  Therefore many commands hang: sudo ifconfig ctrl-alt-f2, computer hangs on shutdown

  get-around:
  in grub, select advanced options, then reccovery
  in menu select root
  at #:
  mount -o remount,rw /
  echo "blacklist wl" >>/etc/modprobe.d/blacklist.conf
  shutdown -r now

  The computer reboots without Wi-Fi

  here's what appears in syslog on boot:
