Same problem on 10.10. Then updated to 11.04 and the bug still happens.
Affect randomly and keys starts to repeat. No chance to go to terminal (ctrl+alt+fx). The system became inusable and almost freeze. Mouse works most of the times, and then allows to do a software reset. If the mouse doesn't work then the only way is a hardware reset.
Affects users with and without compiz (in 10.10) and with Unity and gnome (in 11.04).
