Created attachment 559303 [details] /var/log/messages Description of problem: System crashes completely shortly after gdm login. In some cases you can log on, but if you try to resize some app window it crashes again. When the system crash, you have to make a hard reset. Version-Release number of selected component (if applicable): xorg-x11-drv-intel-2.16.0-1.el6.x86_64 xorg-x11-drv-vesa-2.3.0-2.el6.x86_64 xorg-x11-server-Xorg-1.10.4-6.el6_2.1.x86_64 kernel-2.6.32-220.4.1.el6.x86_64 dracut-kernel-004-256.el6.noarch How reproducible: Always Steps to Reproduce: 1. Switch on the machine 2. Try to log in Actual results: System crash Expected results: No crash Additional info: I have tried the following: 1. Kernel update in favor of BZ#768288 . I saw a comment in the CentOS bug about the same issue which mentions some system crashes. - no success 2. Downgrade to kernel - 2.6.32-131.12.1 - no success 3. There is some ACPI warnings in /var/log/messages - so booting with acpi=off, noapic, etc - no change 4. Initially there was not xorg.conf, so I've created one - with "Xorg -configure". I've tried to boot with vesa, but X server doesn't start at all. There was no change so I removed the xorg.conf 5. There is a bug (BZ#657664) which mentions Q965 and nomodeset, so I decide to give it a try. Booting with nomodeset in grub.conf seems to fix the problem, but according to the Xorg.0.log it is using the vesa driver.
