I don't know whether aufs is related to the problem or not either. But I will dive into it. - I need to make sure that your aufs2-29 is the latest one. Will you show me the output of "git show aufs2-29"? - Enabling CONFIG_AUFS_DEBUG may find the problem. So please try it. - If you have applied other patches to your kernel, please let me know. Since the problem happens on one machine only, we may need to check the memory by memtest (or something). But its priority is not high because the probability is low. By the way, are you "pmlane-ndn"? If so, I will do my best with my appriciation to your donation. J. R.
