The oops is fully reproducible and happens immediately on mount attempt. I think, the data was not even subject to sudden power failure or any such event. Just upon normal reboot it failed to mount. The image (300Kb) can be found here: http://n-a-zhubr.narod.ru/openwrt/jffs2oops.img.gz (hopefully the link works for all, otherwise I can email it personally) Note: the size of erase block is (intensionally) 256K, not 64. Please CC me, I'm not subscribed. Thank you.
