LGB [Gábor Lénárt], 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. ** This bug is no longer a duplicate of bug 131094 Heavy Disk I/O harms desktop responsiveness ** Changed in: linux (Ubuntu) Importance: Undecided => Medium -- 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/268588 Title: Disk I/O is very slow, system freezes for seconds Status in “linux” package in Ubuntu: Incomplete Bug description: For a while (even with previous ubuntu versions as well), speed of disk I/O is unacceptable. I thought it is a problem with my machine, but I have a quite different machine with the same problem now, and also it was quite OK a year (or years?) ago. Even installing a single deb package with dpkg lasts for minutes, other processes trying to access of disk are totally "dead", a single ls command in a terminal can wait for a minute sometimes. Also, sometimes the mouse cursor can't be moved for long seconds. There is nothing suspect in kernel log which can help. During disk I/O top reports wait state for almost all CPU time. Can it be caused by the pata->libata change for example, NCQ or something like this? I have no idea how to improve the situation. I can provide information of course if I know what I should send. Currently these are machines running up-to-date Ubuntu hardy (32 bit). I can say system is totally unusable even with smaller disk I/O load ... Thanks in advance!
