We've setuped 5 devices with EC and VID headers in one page (data offset = 
2048) and 5 devices with EC and VID headers in separate pages (data offset = 
4096).

On all devices the filesystem can became broken.

But a strange thing we've admited. If FS became broken then mounting it by 
hand at boot time in RO mode and then remounting in RW mode repairs the 
filesystem and an assertion and the following 
error disappears:

UBIFS error (pid 462): ubifs_rcvry_gc_commit: could not find a dirty LEB

UBIFS error (pid 495): ubifs_leb_unmap: unmap LEB -1 failed, error -22


Any advices, please.
