With Linux-4.18-rc5 and an Intel BDW GPU, there is a GPU crash at kernel boot
time as follows:
[ 0.349074] [drm] VT-d active for gfx access
[ 0.349078] [drm] Replacing VGA console driver
[ 0.360104] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
[ 0.360108] [drm] Driver supports precise vblank timestamp query.
[ 0.360132] i915 0000:00:02.0: vgaarb: changed VGA decodes:

[ 4.833977] [drm] GPU HANG: ecode 8:0:0xfffffffe, reason: hang on rcs0,
bcs0, vcs0, vecs0, action: reset
[ 4.833983] [drm] GPU hangs can indicate a bug anywhere in the entire gfx
stack, including userspace.
[ 4.833985] [drm] Please file a _new_ bug report on bugs.freedesktop.org
against DRI -> DRM/Intel
[ 4.833988] [drm] drm/i915 developers can then reassign to the right
component if it's not a kernel issue.
[ 4.833991] [drm] The gpu crash dump is required to analyze gpu hangs, so
please always attach it.
