UBIFS crash (was Re: Problems with mtd_oobtest)

To all,

after reading the posts on the mailing list, with similar problems,  I
believe that
Artem was right already in the beginning where he suggested that I am
experiencing
"unstable bit" issue.

If you look at the kernel log, the dump of the empty space, clearly
shows one bit-flip,
where the first word is read as 0xfffffffd, instead of 0xffffffff.

So, at the moment no solution?

Thanks and best regards,
Matej
