Could you please bisect? *** Bug 90252 has been marked as a duplicate of this bug. *** Test with the latest drm-intel-nightly kernel(commit 2a36ab374449e3794b4be6be01f1a47cb6ee5b83)on SNB platform,the issue still exist. Bisect result: Bisect shows 5c5f645773b6d147bf68c350674dc3ef4f8de83d is the first bad commit. commit 5c5f645773b6d147bf68c350674dc3ef4f8de83d Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue Apr 14 17:35:14 2015 +0200 drm/i915: Unify aliasing ppgtt handling With the dynamic pagetable alloc code aliasing ppgtt special-cases where again mixed in all over the place with the low-level init code. Extract the va preallocation and clearing again into the common code where aliasing ppgtt gets set up. Note that with this we don't set the size of the aliasing ppgtt to the size of the parent ggtt address space. Which isn't required at all since except for the ppgtt setup/cleanup code no one ever looks at this.
