Are those new? Maybe the card is not seated correctly? Can you try
another slot?
As for the null pointer defer in the display code, @Wentland, Harry
any ideas? I don't see why that should happen. Maybe some hotplug
pin is faulty or the display has input detection and that is causing
some sort of hotplug interrupt that causes a race somewhere in the
driver? Can you make sure the monitor connector is firmly seated on
the GPU?
