ubi_io_read -74 and ubifs_scanned_corruption errors with i.MX28

Hi,
We're seeing a failed device after running for a few weeks with various
UBIFS errors, including "ubi_io_read: error -74", "ubifs_scan: corrupt
empty space", "ubifs_scanned_corruption", etc (please see the kernel
output below). We're running Linux 3.10.0-rc7 on a Freescale i.MX28 board
with a Micron MT29F2G08ABAEA device.
I tried running some of the mtd tests, and most of them pass, with the
exception of mtd_oobtest and mtd_nandbiterrs (although reading the
archives, it appears these failures may be due to an issue with the tests,
and not necessarily related to the failure below).
Note that we're NOT using ubiformat; but, we don't use nandwrite either
(we flash_erase, then do an ubiattach + mount, then extract a root
filesystem image onto the mounted filesystem). So I'm not sure the "Why
do I have to use ubiformat?" in the FAQ
(http://www.linux-mtd.infradead.org/faq/ubifs.html#L_why_ubiformat)
applies in this case.
And, I'm not sure that it's an issue with sub-pages not being properly
supported, as appending "--vid-hdr-offset 2048" to ubiattach results in
the same failure.
Any ideas regarding what might be going on here? Perhaps we really do
need to use ubiformat? Or maybe the mtd_oobtest / mtd_nandbiterrs test
failures are masking a real issue with the MTD and/or i.MX28 gpmi nand
drivers or configuration?
thanks,
-mike
