--- Comment #1 from Chris Wilson <chris at chris-wilson.co.uk> ---
Note piglit isn't throwing a hissy fit due to i915 probe failing, but the

i915 0000:00:02.0: [drm:i915_gem_init [i915]] Failed to initialize GPU,
declaring it wedged!

which was suppressed in

    drm/i915: Remove function details from device error messages

    Error messages are intended to be addressed to the user; be clear,
    succinct, instructive and unambiguous. Adding the function name to
    that message does not add any information the user requires and in
    the process makes the message less clear.

    E.g.

    [  245.539711] i915 0000:00:02.0: [drm:i915_gem_init [i915]] Failed to
initialize GPU, declaring it wedged!

    becomes

    [  245.539711] i915 0000:00:02.0: Failed to initialize GPU, declaring it
wedged!

So even though we still are flooding dmesg with a KERN_ERR message, piglit
isn't flagging anything wrong in dmesg. Go piglit, go!
