드라이버 설치(MADWIFI)중 에러메세지 입니다.

[root@localhost ath]# insmod ath_pci.o
ath_pci.o: unresolved symbol ath_rate_findrate
ath_pci.o: unresolved symbol ath_rate_newassoc
ath_pci.o: unresolved symbol ath_rate_detach
ath_pci.o: unresolved symbol ath_rate_node_init
ath_pci.o: unresolved symbol ath_rate_setupxtxdesc
ath_pci.o: unresolved symbol ath_rate_node_copy
ath_pci.o: unresolved symbol ath_rate_node_cleanup
ath_pci.o: unresolved symbol ath_rate_attach
ath_pci.o: unresolved symbol ath_rate_tx_complete
ath_pci.o: unresolved symbol ath_rate_newstate

컴파일 후 위와 같이 모듈을 등록하려 하는데 에러메세지가 나옵니다.

어떤 해결 방법이 있을까요?
