Hi Joseph,

Thanks for the quick reply!

Strange error: Just tried to install a nightly DRM build (image +
headers) and encountered an odd dependency when I tried to install the
header:

dpkg -I linux-
headers-3.12.0-994-generic_3.12.0-994.201310080405_amd64.deb

produces the following output:

 Description: Linux kernel headers for version 3.12.0 on 64 bit x86 SMP
  This package provides kernel header files for version 3.12.0 on
  64 bit x86 SMP.
  .
  This is for sites that want the latest kernel headers.  Please read
  /usr/share/doc/linux-headers-3.12.0-994/debian.README.gz for details.


The package depends on itself?!?!? 

Needless to say, installing this will be tricky... :-)

What's the problem? An issue when packaging the deb? BTW: Can I boot the
kernel without the headers installed? I suppose I only need the headers
when going to compile modules from source code or is there any other
reason to install them?

BTW: I encountered the original wifi problem with kernel version
3.9.-030900 back in April already when I gave the the then current
mainline kernel a spin. So not sure if this has been fixed in 3.12...

Title:
  wifi connection drop (b43 eapol timeout)

Status in “linux” package in Ubuntu:
  Incomplete

Bug description:
  Experiencing problems with a BMC4331 wlan chip controlled by the b43
  kernel driver with the following environment:

  - Stock raring with b43 wifi driver on a 3.0.8-31 generic kernel on a Macbook Pro 8,1 (although this problem has  been around since kernel version 3.2),
  - Router is a D-Link 625 with Openwrt Attitude Adjustment (12.09, r36008),
  - Wireless cell is 2.4 GHz with WPA2 PSK authentication.

  The symptoms:

  - Openwrt hostapd issues a WPA rekeying request for the group temporal key (GTK),
  - B43 / wpa_supplicant times out (the router log showing a "EAPOL-Key timeout" error message),
  - Openwrt issues another GTK handshake message,
  - The sequence repeats four times after which the router unauthorises the Mac,
  - Ubuntu drops the connection and wpa_supplicant initiates a re-authentication sequence after a while.

  I have a pretty good idea of what's happening on the router side,  but
  fail to increase the logging level of wpa_supplicant on the Mac.
  "wpa_cli level" rejects any attempts to increase the level from
  "msgdump" to "excessive" so I am at a loss why wpa_supplicant / b43
  fails to acknowledge the GTK re-keying request (the b43 module
  debugging is already turned on).

  First step would be to convince the running wpa_supplicant instance to
  generate more debugging information to see why the request is not
  answered. Happy to provide more information once this is achieved.
