I think you need to attach the ubifs before mounting. See
http://openmoko-public-mailinglists.1958.n2.nabble.com/UBI-success-story-td4218730.html
for the steps, though unless you want to reformat, you shouldn't follow
all of them.

Alternatively, you can follow http://wiki.openmoko.org/wiki/UBIFS :
# apt-get install mtd-utils # if you are on qtmoko
# ubiattach /dev/ubi_ctrl -O 2048 -m 6
# mount -t ubifs ubi0:om-gta02-rootfs /media/om
# ls /media/om
Anyway it could be a problem related to ubifs instability, which is a
topic recently discussed in mailing list [1]. You can follow that tread
and try to:
Guy who'll have ubifs trubles please try to:
1. disable bulk read in fstab and check if problem will still exist.
2. do nanddump and post it or try to reproduce bug with nandsim. (i
guess ubifs guys can fix problem in case if such dump exist quite fast)
Regards
Giacomo
