Comment 2 Jari Tahvanainen 2017-05-23 10:13:50 UTC

Still timeout with 4.11.0-drm-tip-ww18-commit-fb550f8+ (KBL-2-MS-B1421). Execution ends as incomplete (timeout) so with KBL we are back on bug 91454.
With 4.12.0-rc1-drm-tip-ww20-commit-9b25870+ (BSW-1-BRASWELL) and 4.12.0-rc1-drm-tip-ww20-commit-9b25870+ (BDW-1-NUC5i5MYBE) and 4.11.0-rc8-drm-tip-ww18-commit-7f02755+ (HSW-1-D54250WYK) result is fail, tracked on bug 100667, removing BSW, BDW and HSW from here.

Jari the bug 100667 is the same that this, adding BSW in the title due to the test igt@gem_render_linear_blits@swap-thrash keeps fail

In order to be able to close this bug, please test and share results. Thank you.

Comment 6 Humberto Israel Perez Rodriguez 2017-06-27 22:00:43 UTC

with latest commit from drm-tip this test piglit shows as timeout and it was killed by itself if we run it alone, i am wondering if in the latest kernel commits from drm-tip is included the fix ?
