10.3 stable successfully running Haswell graphics

Thu Apr 14 23:30:32 UTC 2016

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:

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.
