Are you willing to try 3.12.9 or 3.13.1 upstream kernel? Let's see if
changing the kernel makes any difference. I don't recall any ext4
problems like this, but maybe it's device driver problem.
The other thing I'd ask is whether you can swap out the hard drive
interface --- can you use a USB 3.0 attached drive, or something like
that?
One final thing that you could try doing, depending on how
easily/quickly you can reproduce the problem, is to use blktrace and
see if you can catch who or what is writing to that specific block
which is getting corrupted.
