Unless you have the original output from the first e2fsck run, it will be quite difficult to determine what actually went wrong here.

It shouldn't make any difference, but it isn't impossible that there is some kind of bug involved, since I doubt this gets tested all too often.  That said, it seems unlikely, since I'm sure it _does_ happen often enough that it would be reported.  It wouldn't hurt to give it a try on the original 32-bit system, but I fear that even if that were the cause the later e2fsck runs may have changed the filesystem enough that it will be hard to recover.
