Touchscreen only works on every second boot

[Darrell Kavanagh]

On first boot, the touchscreen works. After reboot it doesn't. Reboot again and it works. Reboot again and it doesn't work. And so on. I have discovered a workaround, which is to run "echo 1 > /sys/bus/pci/devices/0000\:00\:15.1/remove" before rebooting. With a script containing this command added to /usr/lib/systemd/system-shutdown/, the touchscreen works on every boot.
