This failure is able to reproduce on IVB [root@x-ivb6 tests]# ./kms_flip --run-subtest vblank-vs-suspend IGT-Version: 1.8-g4b81e9c (x86_64) (Linux: 3.17.0-rc6_drm-intel-fixes_0f33be_20140923_debug+ x86_64) Using monotonic timestamps Beginning vblank-vs-suspend on crtc 7, connector 17 1024x768 60 1024 1048 1184 1344 768 771 777 806 0xa 0x40 65000 .rtcwake: wakeup from "mem" using /dev/rtc0 at Wed Sep 24 14:35:27 2014 .rtcwake: wakeup from "mem" using /dev/rtc0 at Wed Sep 24 14:35:59 2014 Test assertion failure function check_state, file kms_flip.c:555: Failed assertion: timercmp(&es->last_received_ts, &es->current_ts, <) vblank ts before the vblank was issued! timerdiff -1235s, 711943us Subtest vblank-vs-suspend: FAIL (2.557s) The testcase is unstable. It often fails on first run, but passes on second run. I unable to bisect. It impacts i965 platforms. (In reply to fangxun from comment #2) > The testcase is unstable.

(In reply to Daniel Vetter from comment #5) > Can you please retest on latest -nightly? We've just merged a few flip fixes. It still fails on latest -nightly kernel.

Bug not reproduced with latest drm-intel-nightly kernel (6817e96) and IGT 1.13 on Sky Lake Y. Not reproduced on BSW with same setup.
