MTD block i/o error while booting linux kernel

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
