dmesg (ArchLinux)

Hello,

After few minutes (3 to 15) of use, the display freezes. 
1 or 2 seconds later, the screen is filled at once with repeated noise small
pattern. Then, display is frozen, no reaction at all to key presses or mouse.
NumLock etc. keyboard lights do not react. Ssh-connection dies. Machine does
not respond to ping. SysRq-keys cannot sync disks. Logs are not written to
disk. SysRq-keys (SysRq-reboot) do not work at all. Have to press reset button. 

The video card is NVIDIA Corporation C61 [GeForce 7025 / nForce 630a].

It does happen with 2 distros : ArchLinux and Ubuntu 15.04. The freeze is best
triggered by lauching LibreOffice or Firefox.

Adding nouveau.config=NvMSI=0 kernel parameter does not help.

Thanks
~~
laurent
