This is happening to me with an USB keyboard on an IBM ThinkPad X41. g-s-d goes to 100% CPU and the numlock led starts blinking in a crazy and irregular way.
The X41 BIOS has the option to keep the internal keyboard numlock separated from the external keyboard one selected; so only the led on the USB keyboard blinks. If I try to enable the internal numlock, it gets disabled as soon as the g-s-d disables the external one.
I don't know if this problem is related to the aforementioned BIOS setting; anyway I've now (temporarily?) solved this by removing the settings plugin for the keyboard as explained earlier in the comments.
