Ok, just did it again, similar bisection log, points at the same commit.

The commit before it:

fb172f5fe880 ("drm/nouveau/gr/gk20a: move MODULE_FIRMWARE firmware definitions")

boots ok but

2dd4d163cd9c ("drm/nouveau: remove open-coded version of remove_conflicting_pci_framebuffers()")

doesn't.

Ideas?
