==Bug detailed description==
-----------------------------
Run 5 cycles on BSW with the latest -nightly kernel. fail rate: 2/5, it also has bug 86767 
It also has following error:
<3>[ 2768.795405] [drm:valleyview_pipestat_irq_handler [i915]] *ERROR* CPU pipe B FIFO underrun

IGT-Version: 1.9-g7848d21 (x86_64) (Linux: 3.19.0-rc6_drm-intel-nightly_70438b_20150128+ x86_64)
Subtest cursor-rotation: TIMEOUT (13.084s)

==Reproduce steps==
---------------------------- 
./kms_rotation_crc --run-subtest cursor-rotation
Comment 1 Thomas Wood 2015-04-22 10:14:33 UTC 
The timeout behaviour of the tests has been changed in commit cff102e (lib: use test failure status for igt_set_timeout). Please re-test with this commit.
Comment 2 ye.tian 2015-04-23 02:54:33 UTC 
Test it on the latest nightly kernel and latest igt (e1ce5ea),this problem does not exists. but this case will fail, I will file as a new bug.

output:
