Hi,
I have tried latest mainline kernel as of today (3.6-rc3) on two different
platforms (ARMv5 i.MX28 and PowerPC MPC5121e) and see similar crashes when
accessing UBIFS volumes (i.e. booting from UBIFS):
Please excuse the lengthy e-mail, I have tried to strip down the error message
hemorrhage to a sensible size, but I don't want to leave out potentially
important information:
On the powerpc platform the errors start like this:

the login prompt (wonder!). Upon fs accesses the following messages are

Hi, looks like a problem with your driver. For some reasons it returns
ECC errors when reading small amount of data (160 bytes). Did you run
mtd tests - to they pass?
So UBI just tells that it cannot read, the root-cause is in the driver.
Did this work in loder kernels? If yes, you can try to bisect.

I thought so at first, but this error appeared on two different hardware
platforms at the same time, when upgrading to latest mainline. I am coming
from kernel 3.1, which worked fine on the MPC5121e. The ARM platform also
worked without problems on a previous version (I think it was 3.4-something,
not so sure right now). The only common piece of hardware/driver is the actual
NAND flash chip on both boards (Samsung K9K8G08... SLC 8Gbit NAND), so I
thought this had to be a (temporary) issue in current mainline code.

Two different drivers... same issue!?
> Did this work in loder kernels? If yes, you can try to bisect.
I am trying to bisect right now. Will report back when I find something. I
just wanted to know if this happened to be a known issue.
Can you tell if I am supposed to be able to mount a UBIFS device formatted
with 3.1 on latest mainline without trouble? Is there a chance OOB layout may
have changed, or something similar? I tried reformatting with 3.6-rc2 just in
case, but the problem remained.
Any suggestion is appreciated.
Best regards,

A change in the mtd layer probably caused this.

Quite possible if there is a bug in mtd layer. First try to find out the
latest working kernel release.

Absolutely yes, we maintain on-flash format compatibility and you do not
have to re-format your flash.

Ok, sounds reasonable.
I found kernel 3.5 works fine. Now bisecting...

Good to know! I had such an issue before, when upgrading our customer from
Freescale's 2.6.25 kernel to 3.1 mainline. Freescale had a different OOB/ECC
layout. The upgrade procedure was a PITA and involved making a filesystem
backup/restore to a USB device :-(

If you want to check whether it is UBI/UBIFS to blame, please, pull the
ubifs-v3.5.git back-port tree and test. The back-port tree contains all
UBI/UBIFS changes which we have done after 3.5.

All of a sudden I am finding myself unable to reproduce the problem. Baffled
and confused, my only two explanations for this is that either somehow while
switching kernel versions the .config file got altered in such a way that
CONFIG_MTD_NAND_ECC_SMC magically changed value or that some cosmic
radiation corrupted _both_ NAND chips at the same time :-(
My apologies for wasting your time.
I'll report back if I ever happen to reproduce this issue.... it might still
be there but just hard to trigger... who knows.
Best regards,
