Summary: Samsung notebook doesn't take keyboard input anymore
after some time

Since kernel major version 2.6.36 my Samsung R40 Cinoso notebook sometimes
looses the ability to use the keyboard. Most times this happens when the
screensaver is active and I cannot enter anything for the password. Remote
login is possible and dmesg is giving tons of these errors:

Any idea? Do you need more logs?
