Just took a look at your dmesg log again, it really does not look like
UBIFS issue. Something has changed so that UBIFS reads all 0xFFs instead
of nodes - may be driver returns bogus data.

If you have a working kernel then you can bisect and find the commit
which broke your system.

E.g., if you know 2.6.32 worked, but 2.6.35 does not, you can check if
2.6.33 works or not. If yes, check 2.6.34. When you find the first
non-working release, you may start using 'git bisect' to find the quilty
commit.
