Disable broken xhci device before suspend and avoid freeze.

system-sleep-xhci.sh

#!/bin/sh
# 
# 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.

if [ "${1}" == "pre" ]; then
  # Do the thing you want before suspend here, e.g.:
  echo "Disable broken xhci module before suspending at $(date)..." > /tmp/systemd_suspend_test
  grep XHC.*enable /proc/acpi/wakeup && echo XHC > /proc/acpi/wakeup
elif [ "${1}" == "post" ]; then

Thanks for creating this gist. When I shut my laptop lid, my system would suspend. However, sometimes it would not resume and I would be forced to press and hold the power button to shut it off. With this script, I no longer have the issue.

thanks. I used it here:

Thank you! This solved my systemd suspend problems with my System76 Oryx Pro running Arch Linux. I too had log entries with

(Trying to add as many keywords as possible to help future searchers. 🙈)

Same problem on dell XPS 13, ubuntu 18.10, thanks a lot !

Solved (random) immediate wake-up after suspend on dell XPS 13, ubuntu 18.10, thank you 👍
Edit It seems i have problems for the Device 0000:00:14.0 (Intel Corporation Sunrise Point-LP USB 3.0 xHCI) and with my bluetooth device your script solved the first one (disabling bluetooth makes it sleep normally).

The edit of your script posted here https://askubuntu.com/questions/1089067/wakes-from-suspend-immediately-when-bluetooth-device-disconnected/1092933 solved both problems for me.

It fixed my Thinkpad P52 on Fedora 30 too. Thanks a lot!

Who knows why some machines have trouble with this and some don't?
