>Description:
---> My bug-report (96739) is missing. <--- The problem is still unresolved so if you delete this PR send me a message please!

When i place a KDE startup script in /usr/local/etc/rc.d 90% of the times i boot and want to goto the console while still booting my system crashes into a infinite loop. (black screen, cooler goes awall)

Also 70% of the time KDE doesn't get any keyboard events after boot (if this happens only CTRL-ALT-DELETE or using the mouse to shutdown works).

ps. this is only recently after installing a few services to work on my intranet project. (apache and mysql server)
>How-To-Repeat:
Install a few services that start automatic while booting (i.e. mysql server, apache, etc)
Create a KDE startup script like this and while the system/KDE is starting press CTRL-ALT-F1 to crash the system. (i think this will only work with HT enabled)

-- /usr/local/etc/rc.d/kde.sh
#!/bin/sh
case "$1" in
        start)
               /usr/local/bin/kdm
                ;;
        stop)
               killall kdm
                ;;
        *)
                echo ""
                echo "Usage: `basename $0` { start | stop }"
                echo ""
                exit 64
                ;;
esac

>Fix:
No automatic KDE startup.. just boot login as root in the console and then run KDE by hand.
