The commit 9dbaab56ac09 ("drm/i915: Exit cherryview_irq_handler() after one pass" seems to be the root cause. git revert 9dbaab56ac09 works fine on top of v4.6 on my Tronsmart Ara X5 Plus commit dd218276595f35a9a3e2fe1d0f1ed34634cac623 Author: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Date: Wed Jun 22 15:23:03 2016 -0700 Revert "drm/i915: Exit cherryview_irq_handler() after one pass" This reverts commit 9dbaab56ac09f07a73fe83bf69bec3e31060080a. Turns out it was a bad idea and was fixed up "properly" in 4.7 but those patches are too big to put into 4.6, so let's just revert it for now.
