For my dev-SKL I'm getting the same dmesg ERROR with only one display connected
connector 48: type HDMI-A-1, status: disconnected
connector 53: type HDMI-A-2, status: disconnected
connector 55: type DP-1, status: connected
while executing kms_cursor_crc suite:
dmesg-fail: igt/kms_cursor_crc/cursor-256x256-suspend
dmesg-fail: igt/kms_cursor_crc/cursor-256x256-random
