Hi,
I am working on 2.6.12 kernel with the latest mtdsnap shot.I have
Samsung nand chip K9F1208UoM and it is on GPIO.Nand chip is detecting
and i am able to mount also. when i mount i get this error messages ,but
it mounts.
BOOT messages....

After mounting if i try to write any thing it writes ,when i REBOOT the
system nothing remains on the chip.Could any body give me some pointers.
Thanks in advance,
