Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 11. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '11'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 11's end of life. Bug Reporter: Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 11 is 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 please change the 'version' of this bug to the applicable version. If you are unable to change the version, please add a comment here and someone will do it for you. 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 I'm closing this WONTFIX and writing it off as part of the general brokenness of Linux kernel memory allocation, since this is just one example of PAFs that show up in high-pressure situations. |
Created attachment 338717 [details] dmesg excerpt showing the page allocation failure Description of problem: A number of page allocation failures in Xorg were witnessed while playing a video and playing around with Compiz plugins. This is on Intel X3100 graphics. Version-Release number of selected component (if applicable): kernel-2.6.29.1-54.fc11.x86_64 mesa-dri-drivers-7.5-0.7.fc11.x86_64 xorg-x11-drv-intel-2.6.99.902-2.fc11.x86_64 libdrm-2.4.5-4.fc11.x86_64 Actual results: See attached for dmesg output. Some graphical corruption (fonts in Firefox) were observed afterwards.
