Just to get this clear - are you connected via ssh and want to use su?
If so, I fail to see why the keyboard would be in play as you need a
pty, not a vty.
Secondly, your logs mention a kbd2 that is disconnected, so where's
kbd1. And finally, why did the person that connected and disconnected
the keyboard leave a root login open?
