Not sure if it's the same hangs, but I see about the same length of a
hang on my Debian wheezy systems when accessing the first file for a
data operation, with rpc.gssd running or not.  Funnily enough this also
happens when trying to read a non-existand file, but not for things like
a simple readdir.

Still looking into it, but being a non-interruptible sleep it's fairly
annoying.

That being said Debian wheezy also only starts rpc.gssd from the init
scripts if it sees a krb option in /etc/fstab, which I don't have.
