The problem still occurs in the latest kernel from that link,
2.6.35-020635rc3.

** Tags added: apport-collected

** Description changed:

  I believe this to be a relatively serious bug. In maverick, if I press
  the printscreen key, the keyboard will stop working until I restart the
  computer. After I hit printscreen, any other keys I press will add this
  to /var/log/messages:
