Message-ID: <4DFF35CC.7070606@mail.ru> Date: Mon, 20 Jun 2011 15:58:04 +0400 From: Nikolai Zhubr <zhubr@...l.ru> To: linux-kernel@...r.kernel.org Subject: jffs2 oops Hello people, I'm getting an oops in (or closely related to) JFFS2 filesystem in stable kernel 2.6.36.4 on ARM with real MTD memory and also in some 2.6.34-12-desktop (opensuse 11.3) kernel on x86_64 with mtdram emulator. 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.
