When the nVidia card was attached, did kldloading i915ikms cause kernel panic? Or was the problem merely X.org not detecting the intel GPU device? I wish I would have kept the dmesg log for that period. But if I remember correctly, both video devices were detected by FreeBSD, the Nvidia Card and the iGPU from Intel. I actually have the xorg.log.., I'll clip some of it except for the relevant information: [ 2462.054] X.Org X Server 1.17.4 Release Date: 2015-10-28 [ 2462.054] X Protocol Version 11, Revision 0 [ 2462.054] Build Operating System: FreeBSD 10.3-PRERELEASE amd64 [ 2462.054] Current Operating System: FreeBSD riotskates 10.3-PRERELEASE FreeBSD 10.3-PRERELEASE #0 r297531M: Mon Apr 4 00:05:47 CDT 2016 root@riotskates:/usr/obj/usr/src/sys/I915 amd64 [ 2462.055] Build Date: 03 April 2016 08:06:13PM [ 2462.055] [ 2462.055] Current version of pixman: 0.34.0 [ 2462.055] Before reporting problems, check http://wiki.x.org to make sure that you have the latest version. ...

The error from Xorg was more than one possible primary device found, no devices detected, no screens found. Even though I selected the primary video as the iGPU from Intel thru the BIOS, it looks like Xorg was confused. The kernel never did panic though, Xorg just never started. I am using a desktop computer, and the Nvidia card was an addon I originally intended to use only as a GPGPU thru Windows. But It became my video card for FreeBSD while I waited for the Haswell port to be completed.
