This is also happening with the latest supported kernel on 14.04 LTS. We are seeing various repeated messages of "Request for unknown module key 'Magrathea: Glacier signing key: 6fca287c2573d09ca32c1980c0d763777a63d4f5' err -11" on some, but not all, machines running this. I guess it relates to the instillation option(s)?
