2440启动内核是出现
end_request: I/O error, dev mtdblock3, sector 912
Buffer I/O error on device mtdblock3, logical block 114
end_request: I/O error, dev mtdblock3, sector 912
Buffer I/O error on device mtdblock3, logical block 114
end_request: I/O error, dev mtdblock3, sector 920
Buffer I/O error on device mtdblock3, logical block 115
end_request: I/O error, dev mtdblock3, sector 920
Buffer I/O error on device mtdblock3, logical block 115
end_request: I/O error, dev mtdblock3, sector 912
Buffer I/O error on device mtdblock3, logical block 114
end_request: I/O error, dev mtdblock3, sector 920
Buffer I/O error on device mtdblock3, logical block 115
然后panic了
原因：
把drivers\mtd\nand\s3c2410.c中
chip->ecc.mode = NAND_ECC_SOFT
改成
chip->ecc.mode = NAND_ECC_NONE
