Though I'm no speed demon at the keyboard, this can mean a few keystrokes that go missing before the computer catches up with me. Sometimes when it catches up, it will get a key which I pressed during the hiatus; and sometimes it will duplicate the last key I pressed before it stopped paying attention. I see similar behavior with the mouse, but I assume the keyboard is a bit easier to diagnose. >How-To-Repeat: See above. >Fix: Unknown. I've tried swapping to a different USB keyboard. I've tried plugging the keyboard in directly to the USB port, instead of via hubs. I've tried console mode instead of X. In all cases, the bad behavior is still present. >Release-Note: >Audit-Trail: >Unformatted:
