I have a similar problem and it's the KVM switch that does it - I solve
the problem by pushing the console switch button on the KVM box then
going back to the correct console using the keyboard key sequence.
Sometimes it's still repeating but the first keystroke when back stops
the repeat.

It's more annoying when you're in the middle of an edit and its the
backspace key that it happens to :-(
