Bug Description

The kernel is still a bit unstable, according to upstream this should fix my recent hangs:

drm/i915/execlists: Always force a context reload when rewinding RING_TAIL

https://gitlab.freedesktop.org/drm/intel/issues/1164
https://gitlab.freedesktop.org/drm/intel/issues/1150

Also there are some more crash patches in 5.6-rc1 that could be cherry-picked back:

76f9764cc3d5 ("drm/i915: Introduce a vma.kref")
bbca083de291 ("drm/i915: Serialise i915_active_acquire() with __active_retire()")

from https://gitlab.freedesktop.org/drm/intel/issues/1201
