That was wrong. The issue seems might be severe and in both cases happens
because
set_fb_on_crtc function in test doesn't get a correct mode, then tries to
create fb with all params set to 0, causing above mentioned assertion:
igt_fb-DEBUG: igt_create_fb_with_bo_size(width=0, height=0,
format=XR24(0x34325258), modifier=0x0, size=0)
(kms_cursor_crc:1512) igt_kms-CRITICAL: Test assertion failure function
kmstest_dumb_create, file ../lib/igt_kms.c:820:
In both cases this happens after probe fails for that connector:
<7>[ 30.889091] [drm:intel_dp_detect [i915]] [CONNECTOR:95:DP-2]
<7>[ 30.921069] [drm:drm_dp_dpcd_access] Too many retries, giving up. First
error: -5
<7>[ 30.921079] [drm:drm_helper_probe_single_connector_modes]
[CONNECTOR:95:DP-2] status updated from connected to disconnected
<7>[ 30.921169] [drm:drm_helper_probe_single_connector_modes]
[CONNECTOR:95:DP-2] disconnected
<7>[ 30.921598] [drm:drm_helper_probe_single_connector_modes]
[CONNECTOR:100:HDMI-A-1]
Also this could be related to this bug I got today:
