Well, it could be the same, but the bug report does seem to refer to the
bug being in kernel series 3.18.  I am just using whatever 3.10 series
kernel comes standard with Centos 7.x.

I don't know anything about bug reports, and I an not familiar with
swapping out kernels in Centos.

BTW, is El Repo another name for the EPEL repository?
