Latitude E7240 & MDT 2013 Update 1 issues

Good afternoon!

Anyone else having issues trying to deploy Windows 8.1 x64 images to their Latitude E7240's using MDT 2013 Update 1? The process keeps bombing out when trying to perform CopyProfile.  I've narrowed it down to a driver issue since deploying the OS to it without any of the drivers found here

won't kill the deployment.  These drivers all worked in MDT 2013.  I'm not sure what logs I should look through to see if there's any possible way of narrowing it down.
