<pre>This seems to be a regression.
Running ubuntu 14.04 development branch. On an old HP G6000 notebook with
GeForce Go 6000, this is NV4E according to my /var/log/Xorg.0.log
With 3.12.0-7-generic everything runs fine. Even basic acceleration in Firefox
and playing games in Steam (like World of Goo or Snuggle Truck - those run
flawlessly). I have OpenGL 2.1 support and Shader Language 1.20 according to
glxinfo
I runs fine on 3.12-x with Mesa 10.0 and also fine with xorg-edergs PPA with
Mesa 10.1.0-devel
However in both cases booting any 3.13 kernel and running the first GL
application like glxgears or starting a game, my system entirely freezes.
Whether I use stock repository or xorg-edgers. So to me this doesn't seem to be
directly Mesa related, there is some problem with kernel 3.13 definitely. It
freezes reproduceable 100%. No problems with 3.12.
Once I could reat a VT after a while, but it didn't react anymore.
3.13 is going to be the kernel for ubuntu 14.04 LTS.
Sorry, this is my first bug report, please be kind. I'm not able to get any log
files after reboot.</pre>
