Comment 559 for bug 752542

Sorry for cross-posting (original post is https://github.com/Bumblebee-Project/bbswitch/issues/37, duplicated here because github doesn't let us add attachments).

I've been using bbswitch for a few months, but when I moved to Fedora 17, reboot stopped working. I finally found a solution ( [see bug 862067](https://bugzilla.redhat.com/show_bug.cgi?id=862067#c3) ).

Here is my system data:
