device-extend

This generic function is no longer supported. Uses of it should be replaced with device-write or device-read. No methods are defined on it, although the generic function still exists. Your code should not define methods on it either. To ensure you have no methods, evaluate

(mop:generic-function-methods #'excl:device-extend)

If that form returns nil, no methods are defined. If it returns a non-empty list, those methods must be found and redefined.
