I have been getting some random X crashes on my laptop. everything this happens. The system freezes for some seconds then am thrown into a black console with the following

*Setting sensors limits                                                                                                                             [OK]

*PulseAudio configured for per-user sessions
                                                               saned disabled; edit /etc/default/saned
                                                                                                                       *checking battery state... [OK]

although the issue is pretty random and hard to reproduce I do notice that it happens more when my system is under load. and the times I remembered it happening I was on a skype video call or using VLC to play video.

My laptop is an Intel core i5 with Arrandale graphic chip, comes with 4 gb of ram.

I am using the generic pae kernel.

here are logs from my xorg http://paste.ubuntu.com/602529/

Has anyone experienced this before?
