JFFS2 oops

[Nikolai Zhubr <zhubr@mail.ru>]

Hello people,

I'm getting an oops in (or related to) JFFS2 filesystem in stock kernel 
2.6.36.4 on ARM with a real MTD memory and I've found that it also 
happens on x86_64 opensuse 11.3 kernel 2.6.34-12-desktop with mtdram 
simulator if 256K erase-block size is specified.

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.
Some logs are attached below.

The image (300Kb) causing this oops 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 
to whoever is interested)
The size of erase block is set to 256K because my device of interest 
does have it this way.

Please CC me, I'm not subscribed.
Thank you.
Nikolai ZHUBR
