Jamie McCracken, 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 (not the daily folder, but the one at the top) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. 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-v3.13-rc4 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. ** No longer affects: linux-source-2.6.22 (Ubuntu) ** 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/131094 Title: Heavy Disk I/O harms desktop responsiveness Status in The Linux Kernel: Fix Released Status in The Linux Mint Distribution: New Status in “linux” package in Ubuntu: Incomplete Bug description: Binary package hint: linux-source-2.6.22 When compared with 2.6.15 in feisty, heavy disk I/O causes increased iowait times and affects desktop responsiveness in 2.6.22 this appears to be a regression from 2.6.15 where iowait is much lower and desktop responsiveness is unaffected with the same I/O load Easy to reproduce with tracker - index the same set of files with 2.6.15 kernel and 2.6.22 kernel and the difference in desktop responsiveness is massive I have not confirmed if a non-tracker process which does heavy disk i/o (especially writing) replicates this yet - will do further investigation soon To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/131094/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
