dmesg 4.10 - fifo write fault
After release of 4.10 kernel i've used that one from here:
<a href="http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/">http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/</a>
with my ubuntu trusty LTS.
Xorg is now crashing whenever my monitors are going to sleep (happens always in
my lunch time) - after returning its crashed and i need todo a hard reset to
get the gpu running again.
This is what is printed to dmesg when this happens (machine is still working
via ssh):

Trying to restart Xorg is unsuccessful.
