I have a similar problem when trying to use Recovery Mode on Ubuntu 10.04, maybe it is related to this one. I did a script to run automatically when the Recovery Mode option is selected on boot. It was working fine for a while on 10.04, but after some updates (unfortunately I can't remember exactly which ones) the prompt got crazy. When asking for passwords it has the behavior described here every character you type it shows the password prompt again. Also when my script asks for input (through read -e) I cannot see what I am typing and I have to press ENTER twice in every entry to continue.
