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

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