setxkbmap freezes Gnome at first key press

Just before Gnome shell is completely started, Ubuntu freezes completely, nothing is clickable. Only mouse moves. It is possible to note that clock freezes to, the seconds stopped. When it returns, I can see this entries on /var/log/syslog:

The same thing occurs when I run setxkbmap manually. I notice that because of a attempt to disable Caps Lock with the script below:

setxkbmap -option caps:none

The Gnome shell freezes the same way when I press the first key after boot. I don't know why. Maybe the culprit is my old hardware.
