I've developed some keyboard weirdness here too that I'm trying to track down. Occasionally, I get dropped characters, multiple characters, or wrong characters. It only happens sometimes, so I'm not really sure if it's a new issue. I'm running Core 7, KDE, and it shows up so far in Firefox.

Subject: Re: Problem with keyboard while typing some characters.

Where do you have this problems? KDE? Gnome? Or on the console? Both KDE
and Gnome have their own keyboard managers which are responsible for the
layouts. If you expect those troubles on the console, use
system-config-keyboard to change the keyboard layout and deactivate the
dead keys.
