Cooler Master Devastator is a poorly designed LED keyboard for using on
FreeBSD/Linux, I did a quick search because I was surprised it wouldn't
The scroll lock key turns on/off the back light, so your console is
freezing because its doing exactly what you told it to do when pressing
the scroll lock button. Its not an issue with FreeBSD not supporting the
LED backlit keyboard, just that they chose a poor key to link the on/off
feature of the LED to when using the keyboard on FreeBSD/Linux. You may
be able to work around it by using scroll lock prior to FreeBSD starting
to boot and hopefully it will stay on.
Someone else might have a better idea for a work around on this.
