Created attachment 522896 [details] Xorg.0.log Description of problem: When playing video in totem, very often the system will lock-up, i.e. no cursor movement, no response to caps-lock, no response to network ping, no sysrq response. Version-Release number of selected component (if applicable): xorg-x11-drv-ati-6.14.1-2.20110525gitfe5c42f51.fc15.x86_64 kernel-2.6.40.4-5.fc15.x86_64 How reproducible: Very often. Steps to Reproduce: 1.Double-click on a video file in GNOME. Actual results: Often, the totem window will start to become realized on the screen, but the system will lock up. At that point, the totem window is partly transparent. Expected results: No lock up. Additional info: Also happens when starting e.g. lbrickbuster2. While trying to diagnose the issue I followed the instructions here: https://fedoraproject.org/wiki/How_to_debug_Xorg_problems#3D_acceleration_issues I tried booting with nomodeset, and this made no difference. I created an xorg.conf file and tried each of these in turn: Option "AccelMethod" "XAA" Option "AccelDFS" "off" Option "DRI" "off" None made any difference to the lock-up behaviour.
Hi, Tim. This could very well be something kernel/DRI related. Please add drm.debug=0x04 to the kernel command line, restart computer, and attach * your X server config file (/etc/X11/xorg.conf, if available), * X server log file (/var/log/Xorg.*.log*; just to be sure, please, check also with grep Backtrace /var/log/Xorg* which logs might be the most interesting ones, send us at least fresh Xorg.0.log) * output of the dmesg command, and * system log (/var/log/messages) to the bug report as individual uncompressed file attachments using the bugzilla file attachment link above. We will review this issue again once you've had a chance to attach this information. Thanks in advance.
There is no xorg.conf file. The X server log file is already attached -- note that none of the available logs contain a backtrace.

FWIW, it seems to work fine in Fedora 16 (kernel-3.1.0-0.rc6.git0.3.fc16.x86_64, xorg-x11-drv-ati-6.14.2-2.20110727git8c9266ed2.fc16.x86_64).
This message is a notice that Fedora 15 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 15. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '15' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 15 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
