일반 rt2571wf 무선랜 드라이버 커널 패닉 입니다...... 도와주세요

현재 리눅스 커널 2.6.21로 작업 중이고 CPU는 s3c2416입니다.

rt2571wf 무선랜 드라이버를 insmod 후 

#ifconfig rausb0 ipaddress 

넣는것 까지는 정상입니다.

그러나 

#iwlist scanning 

으로 AP를 검색한 후 목록에 있는 3com에 접속하기 위해 

#iwconfig rausb0 essid "3com" 을 하면 커널 패닉이 아래와 같이 발생이 됩니다.

이것 때문에 며칠째 고생 중입니다.

고수님들 도움 부탁드립니다.
