Simply, update your kernel up to 3.16
2. For 64-bit system:
cd /tmp/

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16-utopic/linux-headers-3.16.0-031600-generic_3.16.0-031600.201408031935_amd64.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16-utopic/linux-headers-3.16.0-031600_3.16.0-031600.201408031935_all.deb

wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.16-utopic/linux-image-3.16.0-031600-generic_3.16.0-031600.201408031935_amd64.deb

sudo dpkg -i linux-headers-3.16.0-*.deb linux-image-3.16.0-*.deb
Reboot and done.
If for some reason this kernel release doesn’t work properly for you, reboot into previous kernel (Grub -> Advanced -> select previous kernel) and run this command to remove Linux Kernel 3.16:
sudo apt-get remove linux-headers-3.16.0-* linux-image-3.16.0-*
Finally update grub menu:

sudo update-grub
