so it seems like aufs gets extremely unstable when running with my setup.
After attempting to run a du operation or two, the kernel module crashes. I'm
not sure if it occurs before the module crash, but other actions such as
ls will hang. Other people using the system have said that they can still run
ls in subdirectories, however I have not found this to be true. In case it
helps, there are approximately 773,950 files total that are in all of the
source directories.
The output of dmesg is:
