Description of problem: DQ35JO-based systems will hang on startx if the intel driver is used on the -116.el5 kernel. This problem previously happened under a specific set of conditions (and when using the xen kernel) but this is the first time it has happened under the bare metal kernel. The other problem is referenced here: https://bugzilla.redhat.com/show_bug.cgi?id=412691 The system will automatically use the intel driver, even when you run system-config-display --reconfig. Version-Release number of selected component (if applicable): Kernels 116.el5, 115.el5 are affected, kernel 109.el5 is not. How reproducible: Every time Steps to Reproduce: 1. Install -116.el5 kernel 2. reboot 3. startx Actual results: Hung system Expected results: Functional system Additional info: Changing to the vesa driver prevents the problem.
Problem still present in the 117 kernel.
Thanks for the bug report. We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue. Please attach your X server config file (/etc/X11/xorg.conf) and X server log file (/var/log/Xorg.*.log) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link below. Could you please also try to run without any /etc/X11/xorg.conf whatsoever and let X11 autodetect your display and video card? Attach to this bug /var/log/Xorg.0.log from this attempt as well, please. We will review this issue again once you've had a chance to attach this information. Thanks in advance.
I've tried running without any xorg.conf file and the system still hangs. It even hangs on system-config-display --reconfig. I just discovered that the system _always_ hangs under the -117.el5 kernel when I startx, regardless of whether I use the vesa or intel video drivers in my xorg.conf file. I reverted to the -109.el5 kernel as a control and both drivers worked.

I get a hang on X shutdown with x86_64 kernel. It does not hang when start X. Reproducing on same model motherboard. I tried i386 and PAE kernel and I cannot reproduce this. So it is only x86_64 as reported.
I get a hang when I begin the installation on x86_64 from the latest beta tree. This worked just fine under 5.2.
The hang occurs when X starts at the beginning of the install process. It's x86_64 only.

adding the vga=791 option either at boot (pre-install) or in grub (post-install) fixes the issue I was having
