Thanks a lot for providing various information.
Actually I have a machine with a SLUB configured kernel,
but it's not so problematic. I wonder why NILFS hangs so offten
in your environment :)
Joking aside, one of key differences that my colleague
pointed out, is that your kernel is non-smp one.
We'll try your config to get better environment to debug.
