UBIFS errors are randomly seen after reboots

Hi Richard,
I formatted the mtd partition using ubiformat and issued ubiattach on
the mtd partition.

root at router6654A1:~/arm-openwrt-linux# ubiformat /dev/mtd7

ubiformat: mtd7 (nand), size 96468992 bytes (92.0 MiB), 736
eraseblocks of 131072 bytes (128.0 KiB), min. I/O size 2048 bytes
libscan: scanning eraseblock 735 -- 100 % complete
ubiformat: 736 eraseblocks have valid erase counter, mean value is 0
ubiformat: formatting eraseblock 735 -- 100 % complete

Now , I'm seeing altogether different form of errors.
