Then let's focus finding the suspicious module first. It may be aufs,
but I am not sure because
- it happened in find_mergeable_anon_vma() which is out of aufs.
- the stack trace shows that aufs_fault() calls
  find_mergeable_anon_vma(), but there is no such code in aufs_fault()
  actually.
- the crash message shows the kernel is already tainted.
- the debian kernel may be heavily patched and different from vanilla
  kernel.

I'd suggest you to try reproducing with vanilla 2.6.32. If it happens
again then show me the log. I guess it will be different from the
original bug report a little bit.
And where can I get the debian patches?
The base version is 2.6.32.0?
