It looks to me like a BUG(): the code line disassembles to:

   0:	e2486028 	sub	r6, r8, #40	; 0x28
   4:	e3c95003 	bic	r5, r9, #3	; 0x3
   8:	1a000002 	bne	0x18
   c:	e3a03000 	mov	r3, #0	; 0x0
  10:	e5833000 	str	r3, [r3]

and the last two lines are most definitely an intentional null pointer
dereference.  My guess is your kernel doesn't have verbose bug reporting
enabled.

I bet it's this:

        /* We need to avoid deadlock with page_cache_read() in
           jffs2_garbage_collect_pass(). So the page must be
           up to date to prevent page_cache_read() from trying
           to re-lock it. */
        BUG_ON(!PageUptodate(pg));

and caused by that data CRC error.  Over to the MTD guys for further
analysis.

I wouldn't mind except that it would take some time since I have to
carry over patches which may or may not work.
Has this changed in .31?

I got 2.6.31-rc4 and patch it which wasn't painful.
However, no change.
Here are the results: My initramfs initially mount the two nand
partitions and that's where the initial
uncorrectable error comes from.

uncorrectable error :
mtd->read(0x1f658 bytes from 0x2ec09a8) returned ECC error

It would really help if you enabled verbose BUG reporting, so that
people get a clear indication that it's a BUG() statement that's
being hit.

It's worth pointing out that media errors should not cause a kernel
oops or BUG() - especially in the case of a synchronous write.

So one way to look at this is you have the perfect setup at the moment
for jffs2 developers to fix this problem in addition to locating what
ever is causing the CRC errors.

agree. I'll test on this with 2.6.28.4/ .31-rc4.

I have tried this patch before. I think I found a post in april for
it. With it, on occasions it worked but other times
it did not. I will retry it a few more times to refresh myself to be
sure it was not an unrelated issue.

Some thoughts.

Could you try running the torture test from drivers/mtd/tests? Which
platform is that? Are you sure you're running the NAND chip well inside
its timing specs? Does the flash access work from the bootloader?

I recently had similar trouble which disappeared after I switched off
CPU frequency scaling.

I see these tests but I'm not sure how they're used. is their a doc for these?
I'm on a sam9263 platform and I'm sure my timing are within spec.
Infact I stretched
my to be sure it's not timing related. When it works I can see the
files from my bootloader.
Also when it doesn't work, I can still see file fragments.
I briefly tried creating and mounting a ubi volume which worked until
I repeated it with a file
loaded. I get some uncorrectable errors but since I'm not familiar
with this fs and never
used this filesystem before, this could very well be user error.
Thanks.

The come as kernel module, just insmod them and pass at least the 'dev'
param to specify the mtd device you want them to run on. See the first
couple of lines in the individual source files for a full list of
parameters you can use.

If the torture test doesn't complain about anything, it's certainly the
jffs2 people's call.

Is their a problem in just including them in the build and have it run
at startup?
I did so since I don't have module tools in my initramfs.
It's unclear if the failures are because of bad blocks or something else.

I'm not familiar with this either but it would seem that if a block
cannot be verified it would

little more than half could
be verified(?).Bad chip maybe?  Maybe the mtd guys could provide some clues.
