Comment 2 for bug 229128

Here is my xorg.0.log after the crash. I hope this will help you further.

Besides this issue also have had some other problems with my graphic. If I connect external monitor and work with it after some 1 Hour + I get a whiteout, the whole screen gets white and I can't see anything to solve this I must restart the xserver with crl+alt+backspace and log in again.
Also I noticed some problem with switching from X11 to consoles with ctrl+alz+F1 etc. sometimes after hibernate or suspend I get white screen if I try to switch to console from X11. I don't know if this bugs are related to this first bug but they are happening also without any compositing switched on.

I hope someone has an Idea how to solve this problems, for me it seems that intel drivers are very unstable or is it my system?!
