Public bug reported:

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.

** Affects: linux (Ubuntu)
