When I try to shutdown my computer, it seems as though it is trying to
power off, but it immediately reboots instead.
I can circumvent the problem by unbinding the EHCI drivers right before
power off. I created a systemd service to do this automatically. First,
I created a script, '/usr/local/sbin/unbind-ehci-drivers' that the
service will 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=halt.target
[Service]
Type=oneshot
ExecStart=/usr/local/sbin/unbind-ehci-drivers
[Install]
WantedBy=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
Shutdown works now.
