Keyboard knocks out while using special keys

[Dimitri Karamazov]

I'm using a keyboard with some multimedia keys and sleep, poweroff buttons.
I avoid using those, but accidently hitting any of those keys renders the
keyboard to a freezed state, where only solution is to replug to use it again.
This is the case on both X11 and vt, but the connection is never lost, when I
hit the special keys, it just takes no input. Is there a solution to this?
