Ubuntu 16.04 systemd unload modules on sleep

suspend-modules

#!/bin/bash

# Put into /lib/systemd/system-sleep/suspend-modules
# chmod a+x /lib/systemd/system-sleep/suspend-modules

# Create /etc/suspend-modules.conf
# with one module per line

case $1 in
    pre)
        for mod in $(</etc/suspend-modules.conf); do
            rmmod $mod
        done
    ;;
    post)
        for mod in $(</etc/suspend-modules.conf); do
            modprobe $mod
        done
    ;;
esac

Вместо rmmod, я бы использовал modprobe с опцией -r
