Comment 2 Chris Wilson 2019-10-03 11:16:17 UTC 
This one is particularly nasty here due to the inclusive of the ggtt->mutex from using the aliasing-ppgtt. That means we cannot simply break the cycle by removing struct_mutex and then only using full-ppgtt vma for userptr.

    drm/i915: Pull i915_vma_pin under the vm->mutex

here with the aliasing-ppgtt conflating with the ggtt->mutex, it is not so simple.

Happened in 20% of the runs, looks like a major issue.
