I think it is a good idea do dump the flash and save it, just in case.
So the LEB is mapped.
But the TNC points to an an area with all 0xFFs.
Either TNC is incorrect or, the UBI did not map the LEB to the correct
PEB. "Fastmap" would be an easy target to blame for me, but if it is not
used, I'd say the former is more probably.
Enabling full UBI/UBIFS debugging and reproducing the failure could
help.
And please, do save the flash image (use nanddump).
