Please test the attached patch, following instructions from [1] or the
following instructions:
0. Prerequisites.
apt-get install git build-essential
1. Get a copy of the kernel history if you don't already have it.
git clone \
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git
2. Fetch point releases.
cd linux
git remote add -f stable \
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
3. Configure, build, and test 3.2.y.
git checkout stable/linux-3.2.y
cp /boot/config-$(uname -r) .config; # current configuration
# Make sure the acer-wmi is loaded so it doesn't get configured out
# by the next step.
modprobe acer-wmi
make localmodconfig; # optional: minimize configuration
make deb-pkg; # optionally with -j<num> for parallel build
dpkg -i ../<name of package>; # as root
reboot
... test test test ...
4. Hopefully it reproduces the bug. So try the patch:
cd linux
git cherry-pick -x -s 5719b81988f3
make deb-pkg; # maybe with -j4
dpkg -i ../<name of package>
reboot
... test test test ...
Hope that helps,
Jonathan

Subject: acer-wmi: No wifi rfkill on Sony machines
commit 5719b81988f3c24ff694dc3a37e35b35630a3966 upstream.
The wireless rfkill should charged by sony-laptop but not acer-wmi.
So, add Sony's SNY5001 acpi device to blacklist in acer-wmi.
Tested on Sony Vaio
