일반 EZ-X5 부팅시 의문사항

안녕하세요. EZ-X5를 사용하고 있습니다.
부팅시에 몇가지 의문사항이 있어서 글을 남깁니다.
아래는 부팅시에 출력되는 메세지이구요, CD에 있는 zImage, Ramdisk
를 사용했습니다.

1.BAD BLOCK SCAN -> Kernel, Ramdisk Bad Block [1]
>> 이런 메세지도 정상인가요?

2.아래 쪽에
Unable to handle kernel NULL pointer dereference at virtual address 이하
>> 정상적인 경우가 아닌것 같은데요, 문제가 뭔지를 모르겠습니다.

설명해주시면 감사하겠습니다. 그럼...
