While attaching via fastmap we verify whether the found fastmap is as large as we have computed. With preseeded Fastmaps this assumtion can fail since ubinize cannot know the total size of the MTD and uses the number if used PEBs for the calculation. Therefore the found fastmap might be smaller than the kernel expects.
