Reboot hangs on Dell E6220

It’s a common linux problem and I only post about it for my own reference, but reboot hangs with Fedora 16/17 and my Dell Latitude E6220.

To fix add the grub option:


The correct way to do this is to edit /etc/default/grub and then issue:

grub2-mkconfig > /boot/grub2/grub.cfg
