Description Marta Löfstedt 2017-09-19 06:29:08 UTC
Starting at CI_DRM_3099, which is the first 4.14.0-rc1 freeze.
Various em_exec_reloc@basic-* tests sporadically hit dmesg-warn:
[  247.492370] [drm:fw_domains_get [i915]] *ERROR* render: timed out waiting for forcewake ack request.

Probably related to #102850; causal relationship unclear.

Well, so far all runs where the gem_exec_reloc hit the "[drm:fw_domains_get [i915]] *ERROR* render: timed out waiting for forcewake ack request"

there is incomplete on igt@gem_exec_suspend@basic-s3.

This pattern is also visible on:

So is there any chance of getting a bisect for this? We are reasonably confident it started with the rc1 merge.

We haven't seen the issue on any 4.14.0-rc2 based drm-tip in BAT.
