The test is forcing HDMI connector with EDID exposing 3D enabled modes and then doing a mode set using those 3D modes.

(kms_3d:1432) CRITICAL: Failed assertion: ret == 0
(kms_3d:1432) CRITICAL: Last errno: 22, Invalid argument

The code:

for (int i = 0; i < connector->count_modes; i++) {
	int fb_id;
	struct kmstest_connector_config config;
	int crtc_mask = -1;
	int ret;

	if (!(connector->modes[i].flags & DRM_MODE_FLAG_3D_MASK))
		continue;

	/* buffer creation removed */

	ret = drmModeSetCrtc(drm_fd, config.crtc->crtc_id, fb_id, 0, 0,
			     &connector->connector_id, 1,
			     &connector->modes[i]);

	igt_assert(ret == 0);
}

So modeset fails with EINVAL.

The tested resolution is:
(kms_3d:1432) INFO:     1920x1080i 60 1920 2008 2052 2200 1080 1084 1094 1125 0x20015 0x40 74250 (3D:SBSH)

And this is not pruned for forced 3D EDID but as we can see in the logs, after the test exit when we probe actual modes:

Seems like an issue with mode pruning for forced EDID that appears only on ILK. Maybe other platforms are fine with this mode in the first place?

Keeping as medium as it is affecting old platform, seems to be caused by issue in HDMI forcing code and it is for rarely used 3D.

Probably the same as https://bugs.freedesktop.org/show_bug.cgi?id=105595
