dmesg output 3.19.3

I have PowerMac G5 machine with dual PPC. On Debian wheezy Xserver works.
I upgrade to jessie with kernel 3.16 and Xserver stop working. I tested these
kernels:

vmlinux-3.4.106
vmlinux-3.5.7
vmlinux-3.7.9
vmlinux-3.8.13
vmlinux-3.14.37
vmlinux-3.17.8
vmlinux-3.18.10
vmlinux-3.19.3
vmlinux-4.0.0-rc6

It looks like that between 3.5.7 and 3.8.13 something change and DRM part of
nouveau diver and driver stop working:
I tested above kernels and problem is the same this dmesg output is from 
3.19.3
