Description Deepak B 2006-09-10 16:13:30 UTC
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.

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.

Comment 4 Michel Dänzer 2006-09-10 16:28:59 UTC
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 .
Comment 5 Deepak B 2006-09-10 16:54:48 UTC
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.
Comment 6 Michel Dänzer 2006-09-11 01:46:53 UTC
Please attach another X log file without the multimedia modules.
Comment 7 Dave Airlie 2006-09-11 01:54:29 UTC
I'm guessing some problem with the VIA AGP ... I think I've seen some reports of
this...

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.

Are there any software workarounds to this problems?

Are you still having problems with more recent versions of the driver?

Issue untouched for eleven years, closing.
