Description of problem: In recent builds reboot after AI fails. This could be a problem in systemd: http://cgit.freedesktop.org/systemd/systemd/commit/?id=b85bdddafb321fa870b9250a2ff17040d6996061 This fix is not in systemd 197 (which is currently in stable / used). systemd-200 is pending for updates testing, we'll need to wait for this update to land in stable. This can take a time: https://admin.fedoraproject.org/updates/FEDORA-2013-5452/systemd-201-2.fc18.6
A custom build with the packages referenced in the update above are fixing this bug.
Fixed with systemd update
