Sorry for this late reply; wasn’t able to post over the weekend due to some Discourse issue.

What exactly have you tried? The script in /etc/pm/sleep.d or in /usr/lib/systemd/system-sleep? If it’s the former, that’s on me, I guess. The latter location seems to be the correct one.

I also was in the process of writing a message when that Discourse issue started, so here is a better solution, using a systemd service:

  1. Undo all prior changes
  2. Create a systemd service template:
sudo nano /etc/systemd/system/reload_module@.service

Put this in it:

# /etc/systemd/system/reload_module@.service
[Unit]
Description=unload/load %I
StopWhenUnneeded=yes

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=modprobe -rv %I
ExecStop=modprobe -v %I

[Install]
WantedBy=sleep.target

Save the file (CtrlO) and exit (CtrlX).

  1. Reload the service manager:
sudo systemctl daemon-reload
  1. Enable the instance for the module:
sudo systemctl enable reload_module@rtw89_8851be

should output this:

Created symlink /etc/systemd/system/sleep.target.wants/reload_module@rtw89_8851be.service → /etc/systemd/system/reload_module@.service.
  1. Test it:
sudo systemctl suspend

systemctl status reload_module@rtw89_8851be

should output something like this:

(I used a different module for my testing)
