I've tried running these tests, but they don't reproduce it for me
unfortunately (on APL). The original reporter was using 3 displays; is that
the same setup you're using to trigger this with IGT?
Can you trigger this WARN() with 100% reproducibility with any specific IGT
subtest or is it just something that just shows up randomly at different points
while running the tests?
Can you provide the contents of /sys/kernel/debug/dri/0/i915_display_info to
help clarify exactly what your display configuration is?</pre>
