OK, sorry. I got confused by:

   I am interested in why you set '1' to the aufs module parameter "debug".
   If you had not set, this bug would not appear I guess. Did you see
   something wrong without setting "debug"?

… which seemed to refer to that module parameter. Anyway, moving on:

Confirmed! So indeed, this problem only happens when CONFIG_AUFS_DEBUG
is enabled, which is the default setting in aufs4-standalone.git's
config.mk and the Debian aufs-dkms package does not change that.
So let me ask: is it recommended to disable this compilation option
for production use?
