只需将内核升级到 4.8.12 即可
您可以在终端中输入以下内容来执行此操作:
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.12/linux-image-4.8.12-040812-generic_4.8.12-040812.201612020431_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.12/linux-headers-4.8.12-040812-generic_4.8.12-040812.201612020431_amd64.deb
wget http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.8.12/linux-headers-4.8.12-040812_4.8.12-040812.201612020431_all.deb
sudo dpkg -i linux*.deb
sudo reboot
