It happens on all platform with -queued and -fixes kernel. It works well on -nightly kernel.

    drm: Implement O_NONBLOCK support on /dev/dri/cardN

is not yet in dinq
Comment 3 Thomas Wood 2014-11-21 11:27:09 UTC 
The test should be unblocked by commit f6aa80c (tests/kms_flip: add a timeout for the nonblocking-read test) in intel-gpu-tools. This causes the test to exit with timeout status for kernel builds without the commit mentioned in comment #2.
Comment 4 Guo Jinxian 2014-11-24 02:59:16 UTC 
Verified on latest igt(d8078911f63494eba67f8f07ffb56c4bdeae7bc9).
