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.
