"New" BIOS installed (HP  claim that  bootable usb could do the trick
and lost me some time...):

root@Beatles:~# dmidecode -s bios-version && dmidecode -s bios-release-date
68YGU Ver. F.0E
08/27/2008

Then installed bcmwl driver 
sudo apt-get --reinstall install bcmwl-kernel-source

Then blacklisted all b4*, wl and related drivers:
root@Beatles:~# cat /etc/modprobe.d/blacklist-temp.conf 
blacklist b43
blacklist b44
blacklist ssb
blacklist wl
blacklist ssb_hcd
blacklist b43legacy
blacklist brcmsmac
blacklist bcma


Reboot and when modprobing wl I got the same 
....
 kernel: [  214.826743] wl driver 6.30.223.248 (r487574) failed with code 21
 kernel: [  214.826776] ------------[ cut here ]------------
 kernel: [  214.826814] kernel BUG at include/net/cfg80211.h:3343!
.....
Adding attached the "new" kernel bug.

Rebooting (which is tricky due to the kernel state) and tested b43 and
b44 - working, hopefully writing this post from the laptop.


P.S. I found it annoying that wl  requires modprobe ignore install b44 when b44 is my ethernet driver....

  full description of the message in attached file
  (syslog_extracted.log).

  For some reason this also affects the driver for my NIC  and my laptop
  got out of any possible network connection. So instead of configuring
  the wireless card it left me with only "lo" interface :(. I would
  expect properly configured modules for WAN and LAN....

  Luckily  
  apt-get remove --purge bcmwl-kernel-source 
  restores the previous state so I can submit this bug via LAN.

  Now I'm running  Ubuntu 14.10  but the same happened half an year ago
  when I tried to install 14.04 on this laptop.
