Title:
  BUG and shutdown failure with current b43 driver configuration

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  HW & SW:
  - HP Compaq NX6310 laptop
  - Fresh 32-bit 14.04 Xubuntu install (kernel 3.13)

  Use-case:
  - Boot
  - Check dmesg
  - Try to set up WLAN and ethernet
  - Shutdown

  Expected outcome:
  - No BUGs reported in dmesg
  - Ethernet works automatically and WLAN can be set up
  - Shutdown works fine

  Actual outcome (5/5 times):
  - BUG during boot, from free operation in "wl" driver
  - "eth0" and "wlan0" interfaces are missing
  -  machine never powers off

  Additional information:
  - "rmmod wl" doesn't work, states that it's in use, but doesn't tell by what
  - removing /etc/modprobe.d/blacklist-b43.conf gets rid of BUG and hang at shutdown, then kernel just complains about missing firmware
  - after installing b43 firmware, WLAN works fine (I assume that fixed also ethernet, but didn't verify it)

  Btw. (Debian) b43 firmware installer package install script doesn't
  work.  It expects to be able to wget firmware package from internet,
  altough firmware is needed to get networking working in the first
  place. It should take as argument the location of the firmware
  tarball, and try wget only if that's missing.
