Sounds like you tried to configure tunnel keys or 2 tunnels with the same source address. The 6500 requires that an interface be dedicated as a tunnel source in order to be hw switched. The hardware also doesn't support tunnel keys, which is required when you are configuring 2 tunnels between the same devices using the same source/destination pairs.
