   I use our own board Pavo (www.ingenic.cn). We use Linux-2.6.24.3.
The patches on website are not up to date. But that's fine with Jffs2.

   That seems driver problem.

     Be sure /dev/loop0 device only mount once at one time. That mean
you can't mount /dev/loop0 on your board then modprobe g_file_storage
file=/dev/loop0. After that remember first remmod g_file_storage then
mount /dev/loop0 on board again.
     If still the same result, I don't know why : (
