Also fails here on my byt. Not yet convinced this is an igt bug.
Indeed passes on ivb/hsw, and on byt with i915.enable_ppgtt=1.
Please submit result of: # cat /sys/kernel/debug/dri/0/i915_wedged After the failed test.

3e766b8255efb6c994e6501be2af44b4bdc4d191 is the first bad commit Author: Daniel Vetter <daniel.vetter@ffwll.ch> AuthorDate: Tue Sep 23 15:15:51 2014 +0200 Commit: Daniel Vetter <daniel.vetter@ffwll.ch> CommitDate: Wed Sep 24 14:36:57 2014 +0200 igt/gem_concurrent_blit: Only read back a few GTT values Due to the nature of the test, we can be reasonably sure that it is either all copied or not. So we can sacrificing testing the entire buffer for the expected value in order to speed up the test by only testing along the diagonal.

That bisect result is meaningless.
Please double-check the bisect by reverting it. Likely this is an unstable testcase, so please double-check that the last good commit is _really_ good.

Did you run with i915.enable_ppgtt=2? The testcase is valid. It is not an igt bug.
Similar dmesg failure reproduced while running tests below on IVB.

(In reply to Guo Jinxian from comment #11) That's all display issues, probably from testdisplay ... Guo, have you mixed up bug reports? Please check and attach the information requested in comment #10
(In reply to Chris Wilson from comment #10) > Did you run with i915.enable_ppgtt=2? The testcase is valid. It is not an > igt bug.
