Description Maciek Borzecki 2011-06-13 14:27:32 UTC
Description of problem:
GPU intensive tasks (gnome-shell, kde + desktop effects) cause audio crackling. 
A number of reports list the problem, for now there it is unclear whether the radeon KMS is causing it, but disabling KMS definitely resolves the problem (and prevents any graphics acceleration, hence no gnome-shell etc.)

Version-Release number of selected component (if applicable):
mesa-7.11-0.11.20110525.0.fc15
kernel-2.6.38.7-30.fc15
xorg-x11-drv-ati-6.14.1-1.20110504gita6d2dba6.fc15

How reproducible:
always

Steps to Reproduce:
1. run gnome-shell
2. start audio (rhythmbox, example audio test from gstreamer-properties)
3. quickly switch between desktops or keep pressing start (?) key to enter and leave activities screen
  
Actual results:
audio will be interrupted

Expected results:
audio plays without interruption

Thanks for the bug report.  We have reviewed the information you have provided above, and there is some additional information we require that will be helpful in our diagnosis of this issue.

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),
* output of cat /proc/interrupts,
* 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.

let me know if there is anything else needed

Comment 8 Maciek Borzecki 2011-08-03 09:23:39 UTC
Still a problem after updating to kernel-2.6.40-4.fc15.i686, as I reported in related freedesktop bug https://bugs.freedesktop.org/show_bug.cgi?id=28106 switching radeon power_profile to low seems to alleviate the problem

Comment 9 Fedora End Of Life 2012-08-07 16:29:57 UTC
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Fedora's policy to close all bug reports from releases that are no
longer maintained.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:
