Comment 9 for bug 1372482

Throughout all of this I have multiple samba connections to several
CentOS 6.5 machines which all worked great. It was only the connections
to a CentOS 7 machine that have been unwilling to connect.

I will give this kernel a try also, but it might be later... I need to
get some work done while my system is still functioning!
