Any news? I am afraid your problem will be that UBIFS floods to much.
In that case try to enable debugging in the config, but do not enable
any debugging messages. Even with this UBIFS should give useful dumps
when this error happens:

And BTW, we did not test UBIFS well enough on NOR, and never tested
unclean reboots on NOR, but tested them _a lot_ on NAND. So there
may be some problems, but hopefully we can fix them.
