dmesg warning indicating the race
With nonblocking modeset enabled in i915, there's a testcase failure in
kms_atomic_transition and kms_cursor_legacy that shows that nonblocking modeset
can race against hotplug.
Relevant testcases:
kms_atomic_transition.1x-modeset-transitions-nonblocking
kms_cursor_legacy.nonblocking-modeset-vs-cursor-atomic
kms_cursor_legacy.long-nonblocking-modeset-vs-cursor-atomic (same, but more
iterations)</pre>
