Bug#681232: [3.2.20->3.2.21 regression] Atheros WiFi Adapter couldn't find networks "gain calibration timeout"

[Jesse Rhodes <drubo@drubo.net>]

(i) 3.2.21-1 from snapshot produces the gain calibration timeouts.

(ii) so does a rebuild of debian patched 3.2.21-3. 

Other kernels tried so far in order (we'll use "worked" for functional wifi, and "broke" for calibration timeouts):

debian 3.2.0-2 (3.2.20-1) worked
debian 3.2.0-3 (3.2.21-3) broke 
vanilla 3.2.20 worked
vanilla 3.2.21 worked
snapshot.d.o 3.3.0-rc6 (3.3~rc6-1~experimental.1) worked
patched 3.2.y (3.2.25 with previous attached patches) worked 
debian 3.2.0-3 (3.2.21-3) still broke # got paranoid, tried it again

Thanks for clarifying.  I missed that you had tried 3.2.21-3 again.

Could you list the versions you've tested, in order, and what happened
with each for future reference?

Ok, here are two tests to try.

 (i) Am I correct in guessing 3.2.21-1 from snapshot.debian.org
     produces the gain calibration timeouts, too?

 (ii) Here is a way of testing if the build process changed anything,
      by building the same source with the same configuration:

        cd linux

        # fetch Debian-patched kernel
        git remote add debian \
          git://git.debian.org/kernel/linux.git
        git fetch debian

        # configure, build, test
        git checkout debian/wheezy
        cp /boot/config-3.2.0-3-amd64 .config
        scripts/config --disable DEBUG_INFO

        make deb-pkg; # optionally with -j<num> for parallel build
        dpkg -i ../<name of package>; # as root

        ... test test test ...

Thanks again, and sorry for the fuss,
Jonathan
