Fixed: ThinkPad X130e reboots on shutdown

Had a problem with my Lenovo ThinkPad X130e, where instead of shutting down, it would run through the shutdown process, power off for a few seconds and then power back up again. I solved this months ago, when I first got the laptop, however it reoccurred yesterday after I upgraded to Mint 14 RC.

The solution was found on the Arch Linux forums; https://bbs.archlinux.org/viewtopic.php?id=138318

I've implemented something similar for Debian/Ubuntu/Mint:

/etc/init/power-control.conf

# power-control - disable power control on PCI bus prior to shutdown

description     "disable PCI power management"

start on runlevel [016]

task

script
        buslist="pci i2c"

        for bus in $buslist; do
                for i in /sys/bus/$bus/devices/*/power/control; do
                        echo on > $i
                done
        done
end script

Not too sure if the i2c bus requires this treatment as well, but I'll take a look at that after exams.
