I have figured out the problem. The important kernel messages are these: kernel: [drm] Initialized drm 1.1.0 20060810 kernel: [drm] Initialized radeon 1.25.0 20060524 on minor 0 kernel: agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0. kernel: agpgart: Putting AGP V2 device at 0000:00:00.0 into 1x mode kernel: agpgart: Putting AGP V2 device at 0000:01:00.0 into 1x mode kernel: [drm] Setting GART location based on new memory map kernel: [drm] Loading R200 Microcode kernel: [drm] writeback test failed Apparently the agp aperture width setting in my machine's bios is too small. It is by default set to 32MB. This was fine in FC4, but is apparently not enough under FC6. I set the bios value to 256Mb (the max allowed on my machine) and now X works properly with dri enabled. Please feel free to close this bug, although it would be nice if the kernel would not crash under these circumstances. |
Description of problem: X fails to start, machine hangs with dri enabled on radeon RV280. Cursor never appears, keyboard and mouse are unresponsive. Machine requires hard reset. Version-Release number of selected component (if applicable): xorg-x11-drv-ati-6.6.3-1.fc6 How reproducible: Happens everytime Steps to Reproduce: 1. type starx from runlevel 3 2. 3. Actual results: X fails to start and the machine locks up Expected results: X should start Additional info: Please let me know which logs you would like and how you'd like me to collect them. This is on a newly upgraded system FC4->FC6 with all errata applied via 'yum update' I did not experience this problem on FC4. For now, I have commented out the line: # Load "dri" From the module section of my xorg.conf. This allows X to function correctly - although without 3D acceleration.
