Description of problem: I have a Dell Inspiron 5150 with a Radeon Mobility 9000 (M9) and am using the default radeon driver. Whenever I set the AGPMode option to 2 or 4 in xorg.conf, my system freezes. Unfortunately, nothing can be found to be logged. Version-Release number of selected component (if applicable): xorg-x11-6.8.1-12.FC3.21 kernel-2.6.9-1.681_FC3 How reproducible: always Steps to Reproduce: 1. Start X with 'Option "AGPMode" "4"' in device section of xorg.conf with radeon driver. Actual results: System/X freezes. Expected results: X starts with agp set to 4x mode. Additional info: If I start X without the AGPMode option, dri is enabled and agp is set to 1x mode. Other options, such as AGPFastWrite and EnablePageFlip, work fine.

AGPMode and AGPSize are development options which shouldn't really be used by end users. The setting must match what the BIOS is configured to use. If it isn't, then the behaviour is undefined. What is your CMOS set to for AGP mode? Is it hard coded, or configurable? If it is hard coded, then using the AGPMode option is basically undefined, and instability is probable and expected.
AGP mode is not configurable in the Dell BIOS, so I guess I'm stuck at 1x.
Unfortunately, that seems to be the case. ;o/ Setting status to "NOTABUG"
