It’s kernel regression, By bisected, show the first bad commit is 71b7e54 commit 71b7e54f71b899db9f8def67a0e976969384e699 Author: Daniel Vetter <daniel.vetter@ffwll.ch> AuthorDate: Tue Apr 14 17:35:18 2015 +0200 Commit: Daniel Vetter <daniel.vetter@ffwll.ch> CommitDate: Thu Apr 23 21:06:02 2015 +0200 drm/i915: Don't look at pg_dirty_rings for aliasing ppgtt We load the ppgtt ptes once per gpu reset/driver load/resume and that's all that's needed. Note that this only blows up when we're using the allocate_va_range funcs and not the special-purpose ones used. With this change we can get rid of that duplication.

Please open a separate bug for the kms_flip failures.
(In reply to Ander Conselvan de Oliveira from comment #4) > Please open a separate bug for the kms_flip failures. Yes those look like a separate issue. I pushed the patches to igt to fix the original IVB pm_rc6_accuracy failure, so closing this one.
Verified it. File a new bug 90516 for the kms_flip failures.
Closing old verified.
