dmesg 4.10 - fifo write fault

After release of 4.10 kernel i've used that one from here:

http://kernel.ubuntu.com/~kernel-ppa/mainline/v4.10/

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):

Xorg.log does have that:

[    42.993] (WW) NOUVEAU(0): flip queue failed: Device or resource busy

Trying to restart Xorg is unsuccessful.

[  8810.799] (WW) NOUVEAU(0): flip queue failed: Invalid argument


This does not happen with 4.9.6 i've running now.
Anything i should/can provide or try to get this fixed?
