Alright, so here's all the results I got all based on next-20171109 and running on tegra124-nyan-big:
* plain multi_v7_defconfig, passes: https://lava.collabora.co.uk/scheduler/job/981295
* CONFIG_MODULES disabled, fails: https://lava.collabora.co.uk/scheduler/job/981342
* CONFIG_MODULES and CONFIG_DRM_NOUVEAU disabled, also fails: https://lava.collabora.co.uk/scheduler/job/981343
This is the crash in the EC driver that I mentioned before. You need to add the fix for the EC driver to avoid this BUG_ON.
I was able to bisect this manually dancing around the various bugs and it points to this commit ...

drm/nouveau/bar: move bar1 initialisation into its own function
Unfortunately, I cannot revert cleanly on top of next-20171109 and so I cannot confirm.
Ben, we are seeing a hang on Tegra when booting with CONFIG_DRM_NOUVEAU enabled. Apart from the above bisect result, I don't have much else to go on at the moment. Let me know if you have any thoughts or anything to test.
Cheers Jon
