dmesg with drm.debug=0xff
OS: Ubuntu 16.04.4 LTS
Kernel: 4.17.4
CPU: Intel(R) Xeon(R) CPU E3-1275 v6 @ 3.80GHz
MotherBoard: SuperMicro X11SAT-F
The i915 kernel driver is not able to initialize the Intel GPU unless the
Aperture size in the BIOS is set to 128MB or less.
Doing this results in quite some problems for our use case though.
Attached logging (dmesg with drm.debug=0xff) and other information about the
system.</pre>
