file /etc/rc.d/K01test reproduces the problem that this patch addresses.
#!/bin/sh
h_sigterm() {
echo $0 SIGTERM > /dev/console
}
stop() {
local x=0
while true; do
x=$(($x+1))
echo $0 PING $x > /dev/console
sleep 1
done
}
trap h_sigterm SIGTERM
case "$1" in
stop|shutdown)
stop

esac
creating the above file results in a board that cannot complete the 'reboot'
command.
