schoeneicher, this bug was reported a while ago and there hasn't been any activity in it recently. We were wondering if this is still an issue? If so, could you please test for this with the latest development release of Ubuntu? ISO images are available from http://cdimage.ubuntu.com/daily-live/current/ .
If it remains an issue, could you please run the following command in the development release from a Terminal (Applications->Accessories->Terminal), as it will automatically gather and attach updated debug information to this report: apport-collect -p linux <replace-with-bug-number> Also, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. For example: kernel-fixed-upstream-v3.11-rc5 This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag: needs-upstream-testing If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER As well, please remove the tag: needs-upstream-testing Once testing of the upstream kernel is complete, please mark this bug's Status as Confirmed. Please let us know your results. Thank you for your understanding. ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1012806 Title: C1E freezes the desktop and sound Status in The Linux Kernel: Expired Status in “linux” package in Ubuntu: Incomplete Bug description: After a while of inactivity the desktop freezes and sound hangs in a ~1 sec loop. It seems that the interrupt system is caught in a deadlock which is resolved by some external input from mouse or keyboard events. This happens with and without any sound. First I suspected the sound system to cause the issue but after some investigations and searches for similar issues I found out it is related to AMD C1E power saving options. The hanging sound was only a symptom. WORKAROUND: I reverted all the https://wiki.ubuntu.com/Audio/PositionReporting hints and disabled C1E in the bios and that solved the problem. See also https://bugs.launchpad.net/ubuntu/+source/linux/+bug/509219 ---- original, but incorrect issue description: After a while (minutes) sound freezes the desktop, keyboard input or mouse movement fixes it. This is independent of the sound source. It happens with Rhythmbox or youtube or anything else. When the desktop is frozen, the music/audio replays the last second or so, like when an LP/CD gets stuck because of a scratch. I already tried the https://wiki.ubuntu.com/Audio/PositionReporting hints with no success. Thanks for your help!
