Description Marta Löfstedt 2017-10-09 11:03:59 UTC 
On CI_DRM_3190 KBL-shards igt@kms_frontbuffer_tracking@fbc-1p-offscren-pri-indfb-draw-render caused softdog incomplete:  

Note earlier in dmesg:

also:
<3>[  429.024393] [drm:drm_atomic_helper_wait_for_flip_done] *ERROR* [CRTC:36:pipe A] flip_done timed out

So, the issue is likely to have started in an earlier test. However, from cibuglog perspective the bug must be filed to the correct test. Note, this is specifically unfair for test on the shards.

Comment 14 Marta Löfstedt 2017-11-09 07:49:34 UTC 
Note, although there are incompletes here I don't believe are related to the DMC issue it is my intention to close this once the new DMC have arrived.
Same goes for bug 103170 and bug 103165.

Comment 24 Marta Löfstedt 2017-11-23 11:22:46 UTC 
Solution for DMC ver. 1.04 was added to CI_DRM_3375.
https://intel-gfx-ci.01.org/tree/drm-tip/CI_DRM_3375/commits_short.log

I am eagerly awaiting shard results. If OK results I will close.
Comment 26 Marta Löfstedt 2017-11-23 13:13:41 UTC 
CI_DRM_3375 and CI_DRM_3376 has none of:
 "*ERROR* Timeout waiting for engines to idle" nor "*ERROR* [CRTC:36:pipe A] flip_done timed out.", related softdogs. 

I will close this
