Bug#611107: ath5k phy0: noise floor calibration timeout

[REX ABERT <ABERTR@tcc.fl.edu>]

I am attaching the output from dmesg in 3 attachements.

Part 1 is immediately after reboot.

Part 2 is after manually starting wifi after reboot.  (it does not always connect automatically on boot.)

Part 3 is after the system was up for a couple of hours, showing that I was dropped from wifi a few times.

I use this computer for daily work, so as I have time, I'll test different kernel versions.

Rex

Luckily, it seems the answer is "yes" from both submitters.

In order of increasing time commitment, here are some ways to help:

1. What are the newest broken kernel and oldest working kernel you
   have tried?  Please attach full "dmesg" output from booting and
   reproducing the problem with the broken one.

2. If you haven't already tried it, please test 2.6.32-45 from stable
   (I suspect it will behave the same way).

3. Please test 2.6.33-1~experimental.5, 2.6.34-1~experimental.2, and
   2.6.35~rc4-1~experimental.1 from http://snapshot.debian.org/.

4. Please test the attached patches against a 2.6.32.y kernel, such
   as the one from squeeze.  For example, like this:

        # prerequisites
        apt-get install git build-essential

        # get the kernel history, if you don't already have it
        git clone \
          git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

        # fetch point releases
        cd linux
        git remote add stable \
          git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
        git fetch stable

        # configure, build, test
        git checkout stable/linux-2.6.32.y
        cp /boot/config-$(uname -r) .config; # current configuration
        scripts/config --disable DEBUG_INFO
        make localmodconfig; # optional: minimize configuration
        make; # optionally with -j<num> for parallel build
        fakeroot -u make deb-pkg
        dpkg -i ../<name of package>; # as root
        reboot
        ... test test test ...

        # hopefully it reproduces the bug.  So try the patches:
        cd linux
        git am -3sc /path/to/patch-1
        git am -3sc /path/to/patch-2
        make; # maybe with -j4
        fakeroot -u make deb-pkg
        dpkg -i ../<name of package>; # as root
        reboot
        .... test test test ...

  There is an alternative set of instructions at [1].

Thanks, both.

Hope that helps,
Jonathan
