Debian kernel maintainers:

Please consider applying b189e810619a ("8139cp: fix missing
napi_gro_flush") to sid.  In addition to fixing this oops, it would
help the submitter to test the fix, which would mean a quick journey
to the upstream linux-3.2.y tree.

AymanHotmail: here's a simpler recipe. :)

    # prerequisites:
    apt-get install git build-essential

    # grab a copy of the kernel
    git clone -o stable \
      git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git \
      linux
    cd linux

    # check out the linux-3.2.y branch
    git checkout stable/linux-3.2.y

    # configure it
    cp /boot/config-$(uname -r) .config; # use standard configuration
    make localmodconfig; # optional: minimize configuration

    # build and test
    make deb-pkg; # optionally with -j<n> for parallel build
    dpkg -i ../<name of package>
    reboot

    # hopefully it reproduces the problem.  So:
    # apply the patch
    git cherry-pick -x -s b189e810619a

    # build and test
    make deb-pkg; # optionally with -j4
    dpkg -i ../<name of package>
    reboot

    # and you're done!
