ubifs panic with 2.6.39 stable - followup

[Brad Parker <brad@heeltoe.com>]

[sorry for the duplicate post; I tried to post a followup with just
  the url to the pastebin log but for some reason  it got stuck
  waiting for the moderator]

Running and older 2.6.31 kernel with UBIFS I see a panic which appears
to be during recovery of a bad block. The root fs (which is UBIFS)
won't mount and the kernel panics.

I upgraded the kernel 2.6.39-stable, hoping that would fix the problem,
as I noticed a lot of recovery fixes had gone in.  It still panics;
it appears the recovery fails.

I rebooted with "ignore_loglevel" and the output is here:

The board is essentially an Olimex SAM9-L9260, with Samsung NAND.

I'm curious if this looks familiar and if it might be fixed post 2.5.39

thanks for any insight.
