This came to our attention: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=0449641130f5 by way of https://bugs.launchpad.net/ubuntu/+source/linux/+bug/801087 and https://bugzilla.kernel.org/show_bug.cgi?id=32082 "During mount, when we fail to open journal inode or root inode, the __save_error_info will mod_timer. But actually s_err_report isn't initialized yet and the kernel oops." Thanks, -Kees -- Kees Cook Ubuntu Security Team
