Description:
--------------------
Using the latest -nightly

1. /GFX/Test/Intel_gpu_tools/intel-gpu-tools/tests/kms_flip --run-subtest
wf_vblank-vs-modeset

2.$?=4

3. STD-OUT:

Using monotonic timestamps
running testcase: wf_vblank-vs-modeset
Beginning wf_vblank-vs-modeset on crtc 3, connector 7
  1280x1024 60 1280 1328 1440 1688 1024 1025 1028 1066 0x5 0x48 108000
failed to page flip: Invalid argument


4.This phenomenon is very strange.Because it's not be reproduced every time.But
I found some regularity:
(1)When booting ILK and standing after a time (maybe some minutes or
hours),it's to likely be reproduced.
(2)When this happend,running this subcase at the next time or more,this 
phenomenon can not be reproduced anymore.


5.I attached the dmesg.
