Description

This case is to run gfxbench manhattan in qemu VM with virtio-gpu enabled and qemu uses "-display sdl,gl=es". It would cause host i915 gpu hang but recoverable.

I tried to take a apitrace for this which can produce this hang without need to setup qemu guest. https://drive.google.com/open?id=1T6A2d--VnVZBMvM0CvjSa6ecWd50OCmi

Any idea or help on how to debug on this would be appreciated.

btw, I'm not sure if this is related to bug 108898.
