Hi All !
I recently ported JFFS2-MTD-NAND with samsung 16bit NAND flash.
it woks well except power fail case.

i turned it off while writing on NAND flash.
and i found my board died with a bellow  "Kernel OOPS"

------------kernel oops-------------------------------------------------------------------------------------------------------------
raw unchecked node of size 0x64034000 freed from erase block 13 at 0x000340c0, but un0

The "Kernel OOPS" may related to "jffs2_mark_node_obsolete" function.

Anybody did have same experience?
