Hi John, Thank you, elrepo sounds good to know about --
http://elrepo.org/tiki/About says is an extra repository for hardware
support.
Still not clear how to troubleshoot the problem so I know what to
install from elrepo.

I know that a spec file is involved in creating an RPM file; do you
mean that you make your own kernel RPM?
