fix suspend to ram not wake up properly

system-sleep-xhci.sh

#!/bin/sh

# Ref: https://gist.github.com/ioggstream/8f380d398aef989ac455b93b92d42048
# Steps to identify:
# 1. `journalctl`
# 2. `/sleep`
# 3. Check for pci_pm_supend
# 4. For example: xhci_hcd 0000:00:14.0: PM: failed to suspend async: error -16
# 5. to get the device details: take `14.0` and run `sudo lspci -k -nn -v -s 14.0`
# 6. Check for the `kernel_module` in this case, its xhci_pci, and disable it
#
# Ref How to check the module: https://github.com/NixOS/nixpkgs/issues/78286#issuecomment-579452772

# This script should prevent the following suspend errors
#  which freezes the Dell Inspiron laptop.
#
# Put it in /usr/lib/systemd/system-sleep/xhci.sh
#
# The PCI 00:14.0 device is the usb xhci controller.
