"Sticky keyboard" fault?

[Bill Davidsen]

I recently got a pop-up say "Sticky keyboard - disabled" and my keyboard stopped 
working. My first reaction was that the message was translated to English, and 
"stuck key" became "sticky keyboard." Can't think of a sensor for that.

In any case, keyboard was *WAY* disabled, plugging in a USB keyboard didn't 
help, ssh from another machine didn't help (keystrtokes not accepted), and I 
finally had to reboot the machine, after migrating all the guests elsewhere or 
shutting them down. Major PITA.

So is there (supposed to be) a way to clear that? And how does the driver tell a 
stuck key from a user holding a key, like a gamer holding down "F" to fire 
weapons, as I've seen them do. How is it detected, and please may I make it not 
do that? Recovery by boot is a Windows technology, they might have it patented.
