Test it on the latest nightly kernel(87afe9) and latest igt(159562c8), this problem still exists.

Comment 4 Jari Tahvanainen 2017-03-27 14:59:56 UTC

Please check out the latest results on BDW and BSW. AFAIK tests are now having SKIP verdict, not dmesg-warn nor dmesg-fail.

Comment 5 Jairo Miramontes 2017-03-27 19:52:31 UTC

So... as of WW10 results, results for this test in BSW are "skip"
and BDW result is pass... IGT is currently running again on both BSW and BDW, as soon as it's done will check a more recent result.

Comment 6 Jari Tahvanainen 2017-04-19 09:54:27 UTC

Marking resolved+fixed due to WW13 results.
4.11.0-rc4-drm-tip-qa-ww13-commit-5c7479a+ (BDW-1-NUC5i5RYB) 
igt@kms_universal_plane@disable-primary-vs-flip-pipe-a		Pass
4.11.0-rc4-drm-tip-qa-ww13-commit-5c7479a+ (BSW-1-BRASWELL)
igt@kms_universal_plane@disable-primary-vs-flip-pipe-a		Pass
Unfortunately the patchID for fix is unknown.
