Having a dmesg would be nice. One thing I can think of off-hand is
that 3.13-rc has MSI turned on by default. You can turn it off by
adding "nouveau.config=NvMSI=0" to your kernel cmdline. If that
doesn't help, a bisect restricted to drivers/gpu/drm/nouveau should
show the offending commit fairly quickly.

Adding "nouveau.config=NvMSI=0" to the command line fixed the problem.
So it looks like commit 049ffa8ab33a63b3bff672d1a0ee6a35ad253fe8
introduced
it.
Any chance you might mmiotrace the blob (version 325 or later) to see
which registers it fiddles with? Or alternatively, if you have a NVCE
card (you never did end up providing the logs which would have made
that apparent), could you try replacing nvc3_mc_oclass with
nvc0_mc_oclass for the 0xce case in
drivers/gpu/drm/nouveau/core/engine/device/nvc0.c? (and boot without
the MSI disabling.) The switch has already been made for NVC8 in
0bae1d61c75 -- perhaps there are more "odd" ones.

Fails exactly the same.

That's the 0xc3 case... you have a nvce card, not nvc3 -- you would
need to change the NVDEV_SUBDEV_MC line to nvc0_mc_oclass for the 0xce
case.
The dmesg and Xorg.0.log with the problem captured across a ssh link.

Of course it's a GF114.
Made the change and it boots without the command line change.
Great! Care to send a patch?

Here it is.
