Hi, from this link http://www.pbehnke.com/main/node/11, I have managed
to make a shutdown anyway --
For some reason, if the usb controls are set to 'auto', the shutdown-
reboot loop starts. The solution was to make them forcefully turn 'on'.
I have added a function in the /etc/init.d/halt script --
set_usbs_on () {
usbcontrolpath="/sys/bus/usb/devices/*/power/control"
for dev in $usbcontrolpath;
do
echo "Setting $dev: " `cat $dev` "to on"
echo on > $dev
echo ""
done
}
and call it before the do_stop function in the 'stop' switch in "case
$1". Now the machine shuts down.
