Some information of my situation: Operating system: Fedora 16 Beta Xorg version: not sure, but found "X.Org X Server 1.11.1 Release Date: 2011-09-24" in the Xorg.0.log.old file.

When the problem happen: After I login, it may happen when I start a new application, not specific, and even when I typing in the terminal. Below is the Xorg.0.log.old file after crash. I think this maybe caused by the intel graphic driver. But it cause x crash is too harm. It leads me lose a lot of my work.
