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.
