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 ...

commit 7313cfa4f6e30384fa04083698d1e865cf812a6a
Author: Ben Skeggs <bskeggs@redhat.com>

    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
