--- Comment #10 from Chuanxiao Dong <chuanxiao.dong at intel.com> ---
This is GVT-d pass-though by unbind GPU from i915 driver and bind GPU to a
vfio-pci device. And QA didn't use "i915.enable_gvt=1" from neither host or
guest side. So no GVT code is involved.

And this issue is a regression since 4.9.0. The tested 4.8.0-rc2+ doesn't have
this issue. Suggest i915 team to help to investigate this regression.
