Hm, nothing seems to be failing, no GPU hangs. Maybe some coherency issue?:

It's a pure CPU copy through the GTT. Either we incorrectly set the PTE or the hardware is a lie.

priority aligned for igt basic tests on gen7 to High+Critical
Comment 5 Jari Tahvanainen 2016-09-09 07:36:48 UTC
Failure has not been visible on ILK in any of the CI testing runs on last 64 execution rounds (~almost 1 month).
The latest results from today are showing:
CI_DRM_1622/fi-ilk-650 - Result: pass
CI_DRM_1622/fi-ilk-m540 - Result: pass

	
IGT-Version: 1.16-ge4d74f2 (x86_64) (Linux: 4.8.0-rc5-CI-CI_DRM_1622+ x86_64)
Subtest basic-small-bo-tiledX: SUCCESS (0.486s)

Based on the previous I would propose this to be marked as resolved+worksforme. Please comment if you disagree.
