I don't think you are using the driver with my patched applied:

At least before the following trace

[  437.790429] Call Trace:
[  437.790444]  intel_modeset_setup_hw_state+0x1f1/0xfc0 [i915]

I should see a

[drm:i915_drm_suspend [i915]] suspend

message. But I can't see in your log any of the debug messages that I added in
my debug patch. Could be that you are using the wrong kernel (you can
cross-check your booted kernel's version with your git repo by enabling
CONFIG_LOCALVERSION_AUTO) or you didn't update your initramfs.
