I build kernel debs based on Ted's response on ext4 mailing list at

http://kernel.ubuntu.com/~ikepanhc/ext4msg61578/

Please also see

Now running test on d05-4

kernel debs in #42 generates other ext4 error message. I am going to tell if there is patch missing from upstream ext4 or we can response these to Ted.
