Description

After the update to Linux 3.16 i915 drm, Bug 76554 from freedesktop.org

https://bugs.freedesktop.org/show_bug.cgi?id=76554

manifests itself on an Intel(R) Core2 Quad CPU Q9400 with G45 integrated graphics:

drm0: taking over the fictitious range 0xd0000000-0xe0000000
error: [drm:pid1054:init_ring_common] *ERROR* render ring initialization failed ctl 0001f001 (valid? 1) head 05663004 tail 00000000 start 00003000 [expected 00003000]
error: [drm:pid1054:i915_gem_init] *ERROR* Failed to initialize GPU, declaring it wedged

Fortunately Jiri Kosina found a 1-line workaround that is still there in the
Linux 4.0.8 code:

https://bugs.freedesktop.org/attachment.cgi?id=104224

This fix has been verified on the Q9400 machine to at least stop the error messages.
