Created attachment 505114 [details] Smolt profile Description of problem: Xorg freezes randomly on Lenovo X220 with Intel HD 3000 graphics adapter (smolt profile attached), system is still reachable through the network during freeze. I haven't found a reliable way to trigger this bug, but it happens quite often when using QtiPlot (qtiplot-0.9.8.3-1.fc15.x86_64), often after 5-10 minutes of work with scientific data. Switching AccelMethod to EXA or XAA does not fix the problem. Version-Release number of selected component (if applicable): This is reproducing on at least: xorg-x11-server-Xorg-1.10.2-1.fc15.x86_64, xorg-x11-drv-evdev-2.6.0-3.fc15.x86_64, glibc-2.14-2.x86_64, libdrm-2.4.26-1.fc15.x86_64, xorg-x11-drv-intel-2.14.0-6.fc15.x86_64, kernel-2.6.38.7-30.fc15.x86_64: and also: xorg-x11-server-Xorg-1.10.2-1.fc15.x86_64, xorg-x11-drv-evdev-2.6.0-3.fc15.x86_64, glibc-2.14-2.x86_64, libdrm-2.4.26-1.fc15.x86_64, xorg-x11-drv-intel-2.15.0-3.fc15.x86_64, kernel-2.6.38.7-30.fc15.x86_64: How reproducible: random. Steps to Reproduce: 1. Boot the system. 2. Launch firefox, thunderbird, libreoffice, qtiplot, emacs. 3. Try to work. 4. System may randomly freeze at any point, but never freezes immediately. 5. Sometimes identical freezes occur with other sets of applications running. Actual results: Xorg not responding, can't switch to other VTs using Ctrl-Alt-Fn or chvt (via ssh root login), screen not updating, no reaction to keyboard, but mouse cursor is still drawn and responds to touchpad. Expected results: Working system. Additional info: I will attach Xorg.0.log files for different xorg-x11-drv-intel versions with corresponding stacktraces and cuts of gdb output.

I have the same problem on RHEL 6.1 with HD 3000. CPU is Xeon E3-1275 on a Asus P8B WS (new C206 B3 Version) kernel-2.6.32-131.17.1.el6.x86_64 xorg-x11-drv-intel-2.14.0-1.el6.x86_64 When X freezes, the mouse pointer can still be moved. Seems to occur on window operations, e.g. opening or moving a window.

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 It is Fedora's policy to close all bug reports from releases that are no longer maintained.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
