Hello Okajima,
I tried the patch and the kernel no longer starts. In my configuration, when
the kernel starts, it turn on an LED; and on entering rdinit, the LED
blinks. So I can see the kernel is not running because the LED is always
off. I'm sorry I don't have access to the serial terminal at present and
cannot see any messages until sshd starts.
After removing the patch (patch -R ...) it works again. Of course the old
error message is still there.

This is an issue due to the combination of lockdep and aufs.
I'd suggest you to expand several lockdep constants and rebuild your
kernel.
Patch attached.
