crash on 2.6.8.1 (reproducible)

I have a kernel crash on the (afaik) latest kernel version 2.6.8.1, which is reproducible.
The kernel doesn't log anything about the crash.
It occurs when you are unmounting a ext2/3 filesystem which is prepared in a special way:
load it into debugfs read-write and create an inode with the number 2 ( mi <2> , I used to give creation time = 0 and link count = 1), then link that inode to . ( link <2> . ). You can mount that image now, should only see a directory named <2> and your system should crash immediately when you are unmounting that image. I created such an image, which should work:

My ver_linux output:
