There are two machines that are the most consistent with failing (every [[idle run]]). [[fi-hsw-4770r]]: connector 76: type DP-1, status: connected physical dimensions: 0x0mm subpixel order: Unknown CEA rev: 0 DPCD rev: 11 audio support: no DP branch device present: yes Type: VGA ID: DpVga HW: 5.6 SW: 1.48 modes: "1024x768": 60 65000 1024 1048 1184 1344 768 771 777 806 0x40 0xa "800x600": 60 40000 800 840 968 1056 600 601 605 628 0x40 0x5 "800x600": 56 36000 800 824 896 1024 600 601 603 625 0x40 0x5 "848x480": 60 33750 848 864 976 1088 480 486 494 517 0x40 0x5 "640x480": 60 25175 640 656 752 800 480 490 492 525 0x40 0xa This one seems to have VGA dongle connected but it does not have native VGA. Because of that the test fails to realize its VGA and does not ignore it. The dongle is the most naive one possible, just a few pins connected through resistors, so the EDID that DRM sees is faked by the DpVga HW to reflect, the default VGA modes. There is nothing on the other side when using i2c directly. The test has to be fixed so that it is aware of DpVga.

The suspicious thing here are the modes - they are the default VGA ones. The HDMI dummy may be faulty one and fails to talk i2c and the LSPcon HW is faking an EDID. I would advice replacing the dongle.
