BAT fail should be P1.
Is this still happening, or all fixed now with the fbdev refcounting fixes?
Chris, can you confirm it is fixed ? If you don't have time to re-test, please share your configuration (HW & SW) and I will assign a QA member to re-test for you.
This failure has not been visible on CI BSW during August+September. Proposing this to be closed/worksforme (or fixed). Please comment if you disagree.
Still visible on -nightly.
Chris, is there something we could help do to get this visible also on CI? What BSW system you have?

Mostly fixed by commit a667fb402c1e856209bf9e77ba41fc1cf356b867 Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Thu Dec 15 15:29:44 2016 +0100 drm/i915: Disable all crtcs during driver unload, v2. still a small residual leak that Maarten has another patch for.
Maarten any update on patches pending?
Yeah this bug is completely fixed with the following commit to plug the leaks. commit 9b2104f423de5c148749a07e8197dbab4c449877 Author: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Date: Tue Feb 21 14:51:40 2017 +0100 drm/atomic: Make disable_all helper fully disable the crtc.
