Are you sure your timming are correct ?
Try to see if you reproduce the problem with slower timming.

Hi
Using Samsung Manufacturer ID: 0xec, Chip ID: 0xda (Samsung NAND 256MiB
3,3V 8-bit), on at91sam9263 board, with Arm-linux.
Getting the following errors intermittently:-
UBI error: ubi_io_read: error -74 (ECC error) while reading 129024 bytes
from PEB 517:2048, read 129024 bytes
usb 1-1: new full speed USB device number 2 using at91_ohci
UBIFS: recovery needed

UBI error: ubi_io_read: error -74 (ECC error) while reading 106496 bytes
from PEB 782:2048, read 106496 bytes
UBIFS error (pid 1): ubifs_recover_leb: LEB 225 scanning failed
VFS: Cannot open root device "ubi0:root" or unknown-block(0,0)

Same issue when on kernel 2.6.30 and also on "commit
d6c9836c1114242aa89ea228bb1c43c17752b76c" of ubifs-2.6.
I don't have the said problem with Mircon Nand.
Please help to find a solution to this issue. Is it the nand driver
which is the culprit?
warm regards
Nataraj
