Test on latest -nightly kernel, the hang goes away.
 ./kms_rotation_crc --run-subtest sprite-rotation
IGT-Version: 1.7-g4d2f511 (x86_64) (Linux: 3.17.0-rc1_drm-intel-nightly_257d90_20140822+ x86_64)
Test assertion failure function test_plane_rotation, file kms_rotation_crc.c:192:
Failed assertion: igt_crc_equal(&crc_unrotated, &crc_output)
Subtest sprite-rotation: FAIL
Comment 3 Guo Jinxian 2014-08-25 02:17:28 UTC 
Test does not cause system hang on latest -nightly(257d90d13794c2eb545ab0d6c708f21e2a0378b6), but the test fails. I reported bug 83029 to track the failure. close this now.
