Comment 3 for bug 1371469

A few questions:

1) Has this problem always been present for you since upgrading both systems to utopic?
2) Do you have any other systems running utopic that do not manifest the issue?
3) How are you shutting the systems down? Via the Unity menu or via the command line.
4) When you say that the problem doesn't happen immediately after boot do you mean that shutdown is always reliable if the system has just booted?
