I cannot tell for sure, it may. What I can say for sure is that I personally is not very interested in solving problems for too old UBIFS code-base. Well, problems I can reproduce here, in my setup, are OK, but subtle problems which I cannot reproduce here are not OK - I really want to be sure UBI/UBIFS are up-to-date and this is not something we already fixed. BTW, from now on 2.6.24 back-port support is dropped. But it is up-to-date _now_ :-) -- Best Regards, Artem Bityutskiy (Артём Битюцкий)
