There are a number of bugs that have been fixed since Linux 3.4,
and the fixes have not made it into the 3.4.y stable releases.

I just sent an announcement about the Ceph stable branch that's
available in the Ceph git repository.  If possible I would
recommend you try using that for 3.4 testing.  The branch is here:

    http://github.com/ceph/ceph-client/tree/linux-3.4.4-ceph

If you do have troubles I would very much like to hear about it.
And if you don't run into the problems you've been seeing that
would be good to know as well.
