BUG and shutdown failure with current b43 driver configuration

[Eero Tamminen]

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.

I don't have the machine anymore (it wasn't a mine, I replaced XP with Ubuntu for another person) so that I could collect logs. From the bug it should be clear what is the issue (broken driver selected for the HW explicitly by Ubuntu specific blacklist), so setting confirmed as requested by above comment.

HW & SW:
- HP Compaq NX6310 laptop
- Fresh 32-bit 14.04 Ubuntu install (kernel 3.13)
Same outcome (5/5 times):
OR
- Fresh 32-bit 14.04 Ubuntu Gnome install (kernel 3.13)
Same outcome (5/5 times):
OR
- Fresh 32-bit 12.04.5 Ubuntu install (kernel 3.13)

Same outcome always:
- "eth0" and "wlan0" interfaces are missing
- machine never powers off

I could reproduce the problems with Compaq nx6310.
 - internal network card is not working (only in live mode)
 - power off is working only manually after shut down

I tried to run the command: "apport-collect 1327797", but it did not work.
Could anybody help me to solve the problem?

This should be a kernel problem, because Ubuntu 12.04.5 and 14.04.01 has the same kernel file.

Could anybody help me how to fix the following problem:
I have a computer Compaq nx6310
After installing Ubuntu 12.04.05 or Ubuntu 14.04.01 ethernet card is not working, however during live mode and installing it was excellent.
The other problem is that after shut dow the computer never powers off, it computer has to be switched off manually.

Could you please help me?
