Created attachment 127105 [details] Non-wordwrapped crash
The information you are attaching is not enough to proceed here. As advised in the kernel log, can you attach gpu crash dump ? Once you see that a gpu hang is happening, execute the following to get this dump (and then attached to this bug): cat /sys/class/drm/card0/error | gzip > error.gz
That file was empty by the time I got around to reporting the bug. Unless you have an idea of where Ubuntu 16.04 might have saved it, then you can close this bug.

The gpu error state is dumped dynamically and except by invoking that dump, it is not saved likes some log such as kernel. I don't think that Ubuntu is dumping and keeping it. So I am closing it for now, but don't hesitate to re-open if this is occurring again.
