I have a Radeon 8500 DV (R200 BB chip) card. Whenever I enable DRI, the system seems to randomly hang when trying to start X. Detailed symptoms and what I have tried are below. If a freeze/hang does not occur during start, the session seems stable from that point on. If I try to restart X however, it is back to the same issue.. System: Athlon X2 4400+ Asus A8V board (VIA KT800 PRO) AGP Radeon 8500 DV (R200 BB chipset) OS: Fedora Core 5 (tried diffrent kernels, listed below) Symptoms (Barring #1, system is un-responsive in each case and needs a reset): 1. System spontaneously reboots after a startx 2. Blank screen -- LCD is on but nothing shows up 3. Monitor says "Frequency out of range 10.6KHz / 10Hz" 4. Monitor says no input on DVI and goes to sleep 5 seconds later What I have tried: 1. I tried the original X server that came with FC5 (xorg 7.0), tried the latest update (same version of xorg from what I can tell. I don't know what all changed in the rpm), and I also tried (and am currently running) the xorg from rawhide (v. 7.1) 2. I have tried the stock FC5 kernel (2.6.15-1.2054_FC5smp), the vanilla 2.6.17.6 and the vanilla 2.6.17.11 3. I tried the radeon drm module as external and as built into the kernel to ensure that the issue was not the module getting loaded and unloaded each time. 4. I tried the latest drm module (from git) 5. Tried fiddling with BIOS (switching to different AGP modes, turning off fast writes, etc.) 6. Since the logs stop right after "writeback", I tried disabling writeback (no_wb=1 parameter). 7. Have tried booting with acpi=off and with noapic None of the above worked. In addition, I also played with settings in xorg.conf (enable/disable fbdev, set different AGP modes, enable/disable fastwrite, enable/disable RenderAccel, EXA Accel, different colour depth, etc.) those didn't help either. If I set BusType to PCI, X starts up with DRI each time with no apparent issue. However, that severely limits 3D and 2D (especially video) performance.

Created attachment 6902 [details] The system log I have truncated the system log to include only the log for that instance. The log stops after "[drm] writeback test succeeded in 1 usecs" ... next line is "syslogd 1.4.1: restart." from the reset.

Does this also happen if the multimedia modules don't get loaded? Unfortunately, I don't know a way offhand to achieve that other than moving away /usr/lib/xorg/modules/multimedia .
I tried moving /usr/lib/xorg/modules/multimedia/* out of there and restarting with DRI enabled. The problem still occurs .. I tried it a few times and the symptoms varied across the 4 mentioned in the original report -- sometimes reboot, sometimes out of range message, etc.
Please attach another X log file without the multimedia modules.
I'm guessing some problem with the VIA AGP ... I think I've seen some reports of this...
Created attachment 6910 [details] Log for startup without multimedia modules Here is the log from starting up X with DRI enabled and the multimedia modules moved out of the way.
