Hi

`git log v2.6.34..v2.6.37 drivers/mtd/nand/s3c2410.` has only 4 entries a=
nd none of
them look as if they could couse ecc errors.
Have you tried to flash a new ubifs from within the a booted 2.6.37?

I suggest you build your kernel with CONFIG_MTD_NAND_S3C2410_DEBUG=3Dy to=
get more
verbose information on why ECC fails.
