So your kernel has these components,
- vanilla v3.4.43
- your patches
- aufs3.4-20130325

I don't know what your bug is yet, but there are all chances that every
component can be the origin of the bug.  Also all of their combinations.
- vanilla v3.4.43 x your patches
- vanilla v3.4.43 x aufs3.4-20130325
- your patches x aufs3.4-20130325
- vanilla v3.4.43 x your patches x aufs3.4-20130325

Optimistically assuming the first component "vanilla v3.4.43" doesn't
have this problem, you may be able to exclude it.
As you might know, aufs3.4-20130325 is for vanilla v3.4.0.  It means
that "vanilla v3.4.43 x aufs3.4-20130325" can be interpreted as "changes
between v3.4.0--v3.4.43 x aufs3.4-20130325".

If the problem is brand new which means you are the first who has met
it, then there is no fix in any git-log.  But if the problem is already
known and there is a fix for it somewhere, the you will be able to find
it in some git-log.  Such theory can reduce the area for you to
investigate I hope.  This will unchange even if your base version is
upgraded to v3.18.
