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:
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

Freedesktop's Bugzilla instance is EOLed and open bugs are about to be migrated to http://gitlab.freedesktop.org.
To avoid migrating out of date bugs, I am now closing all the bugs that did not see any activity in the past year. If the issue is still happening, please create a new bug in the relevant project at https://gitlab.freedesktop.org/drm (use misc by default).
Sorry about the noise!
