Does it also happen without Option "GARTSize", "AccelDFS" and "DynamicClocks"? If yes, does Option "RenderAccel" "off" or "AGPMode" "1" (or "2", or "8" if it's AGPv3) or "BusType" "PCI" avoid the problem? I debugged the problem further with your suggestions and the results are as follows: the problem persists when I disable GARTSize, AccelDFS and DynamicClocks. It also persists when I try AGP Modes 1x, 2x and 4x (I don't think my system is not AGP 8x capable). However, disabling RenderAccel seems to stop the crash from occurring but I can't be 100% sure. I tested reloading the Engadget page about 30-40 times in Firefox 3.1 with RenderAccel disabled and It didn't crash. Then I re-enabled RenderAccel and I managed to get a crash on the first load of Engadget. When I have RenderAccel disabled, X is very slow at drawing to the screen and it is not suitable for normal use as a workaround. I hope this helps. Thank you for taking the time to help me with this. Please let me know if there is anything else I can do. The bug still persists with Ubuntu Jaunty 9.04 with radeon 6.12.1 and xserver 1.6. In addition to the complete freeze described before, sometimes when the system is not responsive, I will be able to move the mouse cursor but the movement is slow/jerky and clicks and keystrokes or any input is not processed. The magic reset keys and restarting the xserver don't work and the only way to restore the system is to power cycle. Created attachment 24846 [details] [review] Debugging patch: Make RENDER acceleration synchronous In order to try and narrow this down, please apply this xf86-video-ati patch (note that it'll probably decrease performance in general, so don't leave it applied otherwise), then reproduce the problem. If the system doesn't freeze completely, log in from another system via ssh, attach gdb to the X server process and enter the command bt full Then attach the output here. This will probably only be useful if all X server binaries have debugging symbols though. Does this still happen with xf86-video-ati from git master or the 6.12-branch? The crash no longer seems to happen with the latest master code. I don't know what commit changed the behaviour however. I would guess: 22e39392297fa11003df90c175db3c449d8f9853 I was mistaken when closing this bug. This is still a problem with git Master of radeon as of 2009-06-12 (June 12th 2009). I am still experiencing crashes, most easily reproducable by visiting engadget.com with firefox 3.5b4 or newer. The details of the system are Ubuntu Jaunty 9.04, latest radeon git master, kernel 2.6.28, rv350 ATI mobility radeon 9600 pci ID: 1002:4e50. I will be trying the patch suggested and provide more information soon. In response to comment #4 which stated that I should apply the asynchronous patch and try to SSH into the box when crashed to dump the log file, I am unable to login via SSH from another machine because the system is completely hung. The machine is unreachable. Please let me know if there is anything else that I can try to figure out what is going wrong. Did you ever try if
Option "BusType" "PCI"
works around the problem?
Created attachment 27555 [details] [review] Alternative synchronous debugging patch This is an alternative debugging patch which may or may not be better wrt turning the GPU lockup into a hard hang. Running with the alternative synchronous debugging patch seems to stop the system from hanging so I can't get a log of the hang. When I revert back to the unpatched version, I still get the hang. It also appears that running with the Option "BusType" "PCI" stops the hang now, however there is a performance hit so it is not a long term solution. The crash seems to be occurring because I have full page zoom enabled. When the page in firefox is scaled by a non integer value, it causes the crash but when the page is zoomed at 100%, or 200% it loads without crashing. Perhaps there is a rounding problem with some part of the driver that is causing the issue. Any progress on this? I have an identical setup (rv350, intel AGP), which freezes the system hard when browsing image-intensive sites with firefox (i.e. open a few images on railpictures.net and switch tabs a few times). Disabling AGP completely gets rid of it, but makes Xv uselessly slow.

Does this still happen when switching to an older kernel (2.6.33 works for me, for example)? Are there interesting messages in your logs?

Does this still happen Looks like it, yes. > when switching to an older kernel (2.6.33 works for me, for example)? > Are there interesting messages in your logs? Nothing in the logs, nothing over netconsole, just a hard hang. Sometimes very fast, sometimes it takes a whole 2 days. It happens on all kernels (went back to 2.6.28), with or without KMS. Initially the hangs started to appear with a git snapshot of ati-drivers from mid-april 2009 (UMS). eruditehermit, Ubuntu Jaunty reached EOL on October 23, 2010. For more on this, please see https://wiki.ubuntu.com/Releases . If this is reproducible in a supported release, it will help immensely if you filed a new report with Ubuntu by ensuring you have the package xdiagnose installed, and that you click the Yes button for attaching additional debugging information running the following from a terminal: ubuntu-bug xorg Also, please feel free to subscribe me to it.

Created attachment 21229 [details] xorg logfile When I visit Engadget (www.engadget.com) with Firefox 3.1, X freezes and I am unable to move the mouse pointer. The system is totally unresponsive and I am not able to ctrl+alt+backspace to restart X and I am not able to use magic alt+sysreq key sequences to reboot either. This problem is always reproducable. My hardware is a radeon 9600 mobility rv350 AGP. I am using xserver 1.5.2, Xorg 7.4 in Ubuntu/intrepid. This effects both the radeon driver version in intrepid (6.9.0+git20081003.f9826a56-0ubuntu2) and current git master as of 20081216 (December 16, 2008). I have attached my Xorg.0.log with this message.
