UBIFS power down recovery problem

Hi lists,
I'm now testing if UBIFS can survive after power down. After tens of
thousands of boot->power cut->boot test circle, the system finally
can't boot up.
I can't understand:
1. How do some ECC uncorrectable pages appear? According to UBI doc,
it will be wrapped to other PEB when one LEB read report UNCLEAN.
2. How does the "0xef" appear? I dumped out the page, it seems it is
protected by the ECC.
I find UBIFS has the unstable bit problem:
http://www.linux-mtd.infradead.org/doc/ubifs.html#L_unstable_bits
Does this cause the problem?
Regards,
Qiang
