Has this received any attention or is there an existing way to recover
from these types of error?

In devices I'm using, the problem is most apparent when the UBIFS RFS is
mounted with "rootflags=sync" and a large file is copied into that RFS
in Linux.  When the unit's power is cycled immediately on the "cp"
command returning, the ubifsload command in U-Boot fails with the same
error as mentioned by Eric Cooper above.
