So your kernel is vanilla v3.4.43 and aufs is plain 3.4-20130325, right?
As you might know, the last version of aufs3.4 is aufs3.4-20131104.
As a first step, I'd suggest you to use the last version.
And how did you mount aufs?
- upper writable is tmpfs?
- lower readonly is vfat?
- XINO file is on the default place, ie. upper writable branch?
For your information, here are the commits in aufs3.4 after 20130325.
Theoretically, the investigation will be
- check all commits both in aufs3 and aufs4 after 20130325.
- decide which commit is necessary for your kernel.
