Hello List,
we are working on an embedded device running on Linux 2.6.24.6.
We had some devices returned from the field with corrupted UBI partitions on a NOR flash.
The corruption was probably caused by a power cut, but we aren't sure about the root cause of the failure.
We found a similar issue in an old thread from the mailing list where Artem said that UBI on NOR could have some bugs that can lead to such a failure (http://lists.infradead.org/pipermail/linux-mtd/2009-May/025737.html), but no final statements was given on that thread.
Any help would be appreciated, thank you.
Here it is a portion of the log captured from a faulty device:

I believe the final statement of the referred thread was that one
of the problems was UBI/UBIFS assumes a (CFI) write buffer size of
8 bytes. This is often not the case with NOR flash. It did not lead
to kernel patches though.
Lateron this problem was found (again) by Anatolij Gustschin
(see the thread "UBIFS partition on NOR flash not mountable after power cut test"
from december 2010) and he fixed it properly. His patches ended up in the mainline.
Btw. it could be your problem is another or a related ubi/ubifs NOR flash power
cut problem. Some other problem have been found and solved as well (mostly by Artem
and Anatolij).
If you update to the ubi/ubifs backported linux-2.6.32 (this is the oldest one
still available) which can be found here:
http://git.infradead.org/users/dedekind/ubifs-v2.6.32.git
you'll probably be fine.

Norbert,
thank you very much for your quick support.
I've downloaded the ubifs-v2.6.32.git linux as you suggested us, but I see a lot a differences regarding UBI with our very old 2.6.24.6 kernel.
Do you think this is the only work we can do? Are there other possible solutions to fix the issue we have? (Like for example applying the patch showed in http://lists.infradead.org/pipermail/linux-mtd/2010-December/033322.html) ?
Thank you again
Daniele Bosi

I believe the final statement of the referred thread was that one
of the problems was UBI/UBIFS assumes a (CFI) write buffer size of
8 bytes. This is often not the case with NOR flash. It did not lead
to kernel patches though.
Lateron this problem was found (again) by Anatolij Gustschin
(see the thread "UBIFS partition on NOR flash not mountable after power cut test"
from december 2010) and he fixed it properly. His patches ended up in the mainline.
Btw. it could be your problem is another or a related ubi/ubifs NOR flash power
cut problem. Some other problem have been found and solved as well (mostly by Artem
and Anatolij).
If you update to the ubi/ubifs backported linux-2.6.32 (this is the oldest one
still available) which can be found here:
http://git.infradead.org/users/dedekind/ubifs-v2.6.32.git
you'll probably be fine.

I would update to the ubi/ubifs backported v2.6.32 because:
- the ubi/mtd CFI buffer write patch involves several patches, with one or two
patches/updates lateron
- other NOR flash (power cut) problems were solved as well and you're not sure
which one hurts you
Actually, we are very lucky Artem still maintains (or maintained?) ubifs-v2.6.32.git
since v2.6.32 is more than 3 years old.

I dropped all the 2.6.* kernels 2 months ago. They are almost up-to-date
so fare, though.
