Hi Matt, thanks for the report.

Does the WARN appear only after a cold start and not after a warm start?
Could you provide a drm.debug=14 dmesg log after cold start with the change in
comment 2?
What is the ME firmware version on your machine? It should be visible in the
"Platform Information" menu in the BIOS setup.
Do you have any AMT features in BIOS enabled or use any redirection like SOL,
IDEr? These are questions from AMT people who are trying to figure out why KVM
would be active at all.
