--- Comment #1 from Ilia Mirkin <imirkin at alum.mit.edu> ---
The ultimate issue is a modeset failure:

[   107.379] (EE) modeset(0): failed to set mode: No space left on device

Pretty sure that nouveau's not involved since there are, it seems, no
connectors hanging off the NVIDIA device. Try booting one of the failing
kernels with

drm.debug=0x1e

which should hopefully reveal more information about what's going wrong.
