Looks like something isn't quite right:

------------------

Done.

------------------

I'm running the latest kernel from updates (with all previous versions removed).

[root at eltest wberrier]# uname -a
Linux eltest 3.10.0-123.13.2.el7.x86_64 #1 SMP Thu Dec 18 14:09:13 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

------------------

But, I was able to load the lirc_serial module in a vm just fine.

------------------

On a different machine (one that I actually have a remote hooked up
to), I'm getting this for some reason:

[ 5339.248363] Request for unknown module key 'The ELRepo Project (http://elrepo.org): ELRepo.org Secure Boot Key: f365ad3481a7b20e3427b61b2a26635b83fe427b' err -11
[ 5339.248461] lirc_serial: disagrees about version of symbol lirc_register_driver
[ 5339.248464] lirc_serial: Unknown symbol lirc_register_driver (err -22)

But, that's a pxeboot nfs root machine, which has been a bit finicky,
so it may be related to something else, I'm not sure just yet.

uname -a
Linux myth 3.10.0-123.13.2.el7.x86_64 #1 SMP Thu Dec 18 14:09:13 UTC 2014 x86_64 x86_64 x86_64 GNU/Linux

(same kernel version as above)

------------------

Ideas about the module installation and "disagreeing symbol version"?
