If you’re using Windows drivers for your hardware, you probably use ndiswrapper.
Unfortunately, ndiswrapper version 1.5.8 cannot compile on kernel version 3.9.x, which is the version that comes with the latest Update Pack, and exits with this message: “too few arguments to function ‘add_taint'”
I just uploaded a patched version of ndiswrapper-dkms to our repositories.
So, if you need ndiswrapper with kernel 3.9.x, open a terminal and run these commands:
sudo apt-get update
sudo apt-get install ndiswrapper-dkms
