Hallo,
ich versuche den Kernel mit einer Veränderung zu kompilieren. Der Compiler gibt folgende Fehlermeldungen aus:
undefined reference to 'netpoll_print_options', undefined reference to 'netpoll_setup' and undefined reference to 'netpoll_send_udp'.
In "shamu_defconfig" habe CONFIG_NETPOLL schon aktiviert. Kann mir jemand weiterhelfen??
