S2410 ez_image를 이용한 ramdisk write시 kernel panic 발생 문의 드립니다.

안녕하세요.

ramdisk file을 생성후 bootloader에서 tftp를 이용해 tfr command로 wirte하면 정상적으로 부팅이 되는데,
이 ramdisk file을 nfs로 복사한 후에, ez_image -r command로 write하고 재부팅하면 kernel panic이 발생합니다.

확인 부탁드립니다.
ez_image 문제 같아서 access_nand module을 찾고 있는데, 안 보이네요.
링크좀 알려주시면 고맙겠습니다.

그럼 수고하세요.
