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.
So it looks like commit 049ffa8ab33a63b3bff672d1a0ee6a35ad253fe8
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.
