Comment 1 Marta Löfstedt 2017-09-26 10:11:12 UTC
Probably related to BUG 102996.
Comment 2 Chris Wilson 2017-09-26 10:45:27 UTC
Note the end of the dmesg shows signs of fs corruption; an uncaptured panic?
Comment 4 Marta Löfstedt 2017-10-03 12:52:08 UTC
Now also incomplete on:

https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3166/fi-ctg-p8600/igt@kms_pipe_crc_basic@hang-read-crc-pipe-a.html

This also has the: "[drm:drm_atomic_helper_wait_for_flip_done] *ERROR* [CRTC:36:pipe A] flip_done timed out" print I have seen this pattern on some KBL incompletes, but there pstore is working and we will see softdog triggered.

This trend is continuing still solid line of incompletes up to CI_DRM_3261.
Theory is that it started when we wnet up to 4.14.0-rc5+,
so someone should do a bisect.
Comment 10 Elizabeth 2017-11-14 20:06:19 UTC
Rising priority since it is BAT.
Comment 11 Marta Löfstedt 2017-11-16 06:38:41 UTC
The incompletes on igt@gem_exec_suspend@basic-s3 has continues since 4.14.0-rc5+. However, from CI_DRM_3350 we added kernel config CONFIG_ORC_UNWINDER to improve stacktraces and from that run CTG no longer incompletes on the igt@gem_exec_suspend@basic-s3. on 2 runs it has incompletes on  igt@kms_pipe_crc_basic@suspend-read-crc-pipe-b instead, but the coverage is significantly improved.

Comment 17 Marta Löfstedt 2018-01-25 12:41:51 UTC
This is a meta bug for Incompletes on CTG.
Comment 18 Marta Löfstedt 2018-01-25 12:49:20 UTC
This is a Meta bug to capture all unexplained incompletes on CTG
Comment 20 Marta Löfstedt 2018-04-10 12:38:35 UTC
Why has this high priority?
Comment 21 Jani Saarinen 2018-04-10 12:44:49 UTC
This should not as CTG. Re-prioritizing.
Comment 22 Francesco Balestrieri 2018-07-03 14:58:57 UTC
This is a metabug with no issues blocking it, no point keeping it around. Closing.
Comment 23 Martin Peres 2018-07-27 13:20:30 UTC

Well, we have plenty of meta bugs like this, and they are here because the issues keep on happening... So yeah, we need to keep it open.

Then perhaps we need to track this differently, e.g. with a specific "incomplete" label + platform field, if your purpose is to have a list of incompletes on this platform. I don't see the point in keeping a bug open for things that may happen in the future.
Comment 25 Francesco Balestrieri 2018-08-14 07:49:04 UTC
I'm at least moving this to lowest priority since there is no action required at the moment.
