Nouveau graphics on my system (Gentoo) often freezes with errors in dmesg.
The system works fine for some time, but starts freezing at random intervals (after 3 mins or 10 mins or 2 hours of work, etc) in random windows (chromium, krusader, smplayer, login screen after auto-lock, etc) and a lot of artifacts appear on the screen. After about 30 secs it freezes completely. My keyboard does not react to any key combinations, mouse pointer moves with lags and mouse buttons do not work so only hard reset helps.
For example, here are two photos of my frozen screen with artifacts: http://i.imgur.com/vTbrNay.jpg http://i.imgur.com/YIvEBGn.jpg
I wrote a script that saves dmesg to a file each 5 secs to get error logs. Please find two examples with different errors attached.
I use the following versions of packages: media-libs/mesa-12.0.1 x11-base/xorg-drivers-1.18-r1 x11-base/xorg-server-1.18.4 x11-drivers/xf86-video-nouveau-1.0.11 x11-libs/libdrm-2.4.70 sys-kernel/hardened-sources-4.7.10
My graphics card is Nvidia GeForce GTS 250 (G92 chip).
