Public bug reported: The problem is that when I copy files to the disk (above to ~50MB and tested from konsole or dolphin), the system becomes slow and unusable until the task is complete. Also, copying the file takes a long time to complete. Once the copy is finished, everything is normal again. I have also noticed that with other tasks that require the use of the disk you get a bad system performance, for example when installing programs. I installed an earlier version of Karmic kernel (2.6.31-11.36) and these problems do not happen, everything works fine with it.
I have installed Kubuntu 9.10 Karmic Koala 64 bits (upgraded from 9.04 Jaunty), ext3 filesystem. $ uname -a Linux nullpc-desktop 2.6.31-14-generic #48-Ubuntu SMP Fri Oct 16 14:05:01 UTC 2009 x86_64 GNU/Linux $ cat /proc/version_signature Ubuntu 2.6.31-14.48-generic ** Affects: linux (Ubuntu) Importance: Undecided Status: New -- System becomes slow while copying files to disk using 2.6.31-14.48 kernel and amd64 https://bugs.launchpad.net/bugs/478557 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
