kernel log with drm.debug=1

Playing in spec ops: the line from steam causes gpu lockup.

Behaviour differs. Firstly system freeze, after a few seconds screen becomes
black. Sometimes works only sysrq, sometimes i can switch to VT and log in
(screen still is black, but sudo reboot works). Sometimes it unfreeze and
everything works again.
