To make the shutdown work, I created a systemd service that will run
whenever the halt.target or the shutdown.target is to be reached. Since
I need to unbind the EHCI drivers, I named the service, naturally,
'unbind-ehci-drivers'.
First, I created the '/usr/local/sbin/unbind-ehci-drivers' script, which
the service must execute:
-----</usr/local/sbin/unbind-ehci-drivers>-----
#!/bin/sh
DRIVER_DIRECTORY='/sys/bus/pci/drivers/ehci-pci'
cd "${DRIVER_DIRECTORY}"
find -mindepth 1 -maxdepth 1 -name '*:*:*.*' -type l -printf '%f\0' | xargs -I
'{}' --null echo '{}' > unbind
-----<srevird-iche-dnibnu/nibs/lacol/rsu/>-----
Next, the '/etc/systemd/system/unbind-ehci-drivers.service' systemd
service file:
-----</etc/systemd/system/unbind-ehci-drivers.service>-----
[Unit]
Description=Unbind EHCI drivers upon system shutdown
DefaultDependencies=no
Before=shutdown.target halt.target
[Service]
Type=oneshot
ExecStart=/usr/local/sbin/unbind-ehci-drivers
[Install]
WantedBy=halt.target shutdown.target
-----<ecivres.srevird-iche-dnibnu/metsys/dmetsys/cte/>-----
With these files in place, the following command will enable the
service:
root@localhost# systemctl enable unbind-ehci-drivers
Optionally, verify if the service is now enabled:
root@localhost# systemctl is-enabled unbind-ehci-drivers
Two other commands that will show more details about the service:
root@localhost# systemctl --all list-units unbind-ehci-drivers.service
root@localhost# systemctl list-unit-files unbind-ehci-drivers.service
Shutdown works now.
