Created attachment 408445 [details] lspci -v Description of problem: After system is running about 60 minutes and at this time is playing video or audio with Firefox(flash) or Mplayer/Totem, system extreme slowdown after interrupt IRQ handle first with graphics card when was play video or interrupt IRQ sound card when was play audio. After first interrupt IRQ about 15 minutes i have second interrupt IRQ with sound card when first interrupt IRQ was graphics card or had second interrupt IRQ with graphics card when first was sound card.

This message is a reminder that Fedora 12 is nearing its end of life. Approximately 30 (thirty) days from now Fedora will stop maintaining and issuing updates for Fedora 12. It is Fedora's policy to close all bug reports from releases that are no longer maintained.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 '12'. 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 12'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 12 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
This error does not occur in the kernel-2.6.32.23-170.fc12. This bug can be closed.
