the interface isn't there. ifconfig looks at the kernel to see what
really exists and tells you the interface is still there. Try the
--force option to ifdown and see if it helps. With my connection I
have a command setup in /etc/network/interfaces to run just before the
interface is deconfigured. If I cancel that command (ie ^C) then the
interface isn't really taken down but ifdown thinks it is.
