Hi. Make sure you have all the security updates installed and that you have the latest version of linux-image-3.2.0-4-amd64, otherwise the problem might be already fixed and we are running in circles.
At this moment it should be 3.2.81-2, you can check this here: https://packages.qa.debian.org/l/linux.html Left frame -> versions: -> old-sec Even if you have all the security updates installed, you should also reboot if you upgraded the kernel after you rebooted for the last time.
