i915 crash dump

On Linux 4.12-rc3 with GVT-g enabled, MDEV device attached to a VM and running
an application using VA-API to watch H264 video I got the following GPU hang:

[71153.016783] [drm] GPU HANG: ecode 9:0:0x85dffffb, reason: Hang on rcs,
action: reset
[71153.016784] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[71153.016784] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[71153.016785] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[71153.016785] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
