Summary: ubifs issues while updating kernel. 2010r1-rc5 mounted nand
Details:
After updating to the later kernel from 2009 I am having many issues with my mounted nand partition Data. It is using ubifs. I have reformatted and cleaned the partition and still get the following output. This partition works great when I use the previous kernel. The error causes the file system to be read only.

Follow-ups
--- Aaron Wu 2011-10-25 01:21:00
UBIFS is tested for 2010R1 release, please check the attached logs, one for
bf537 and another for 548.
--- Chris Page 2011-10-25 11:54:59
I can see and verify that it has been tested. It does not mean that there is not
a bug. Here is the start-up of my the previous 2.6.28.10-ADI-2009R1-svn7850. It
has NO ubi errors on the same board. To reproduce the bug on version 2010R1-RC5
I clean and format the partition. After around two resets the ubi is corrupted.
Comparing the initial output of the two the only difference is that the max/mean
erase counter is different.

After further testing there seems to be an issue with the ubi/nand driver and
large nands. When I use the later kernel with a smaller nand device it seemed to
work fine. I went from using a NAND04GW (4Gbit) which gave me errors to a
smaller NAND512 (512Mbit).
The driver does not appear to handle large partitions. When I use a 400M BYTE
partition and move large files (10 M BYTES) back and forth from the nand I get
these errors and the partition becomes read only. I Noticed you were using a
small nand with a small partition (around 2 M Bytes) and tested using small
files.
Have you tested large NAND memory with large files? The file system should be
able to handle this.

Close this bug since it's not a issue happens on the ADI platform and release.
For customer board support please go to the new engineerzone support community.
For New Nand of diffrent pagesize, erase block size, device size etc you may
need to port the NAND MTD driver first and make sure it's working fine.
