To damian-sawiicki: Do you see a zram-config.conf file under /etc/init ? Another stupid question: did you precisely invoke "dpkg --purge zram- config" ?
(When I realized I still had zram-config at work after uninstalling it, I didn't think about "dpkg --purge" and just removed whatever "zram" files I found in the system, especially /dev/zram0 and /dev/zram1 as the machine has two cores, and eventually zram-config.conf if it was still there, but I am not even sure it was still there). To Luis Henriques: I installed the generic i386 kernel and headers in a P4, and it has also been installed to a T60 where it was running with many programs at same time and zram-config installed and at work. All this lasted about 45 minutes and the session didn't fail, although some swapping was occurring. No buffer I/O occurred. Now I am being testing in the P4, zram-config reinstalled, your kernel i386 generic installed, since about 15 minutes. Are running: Libreoffice writer, Firefox, Software Center, PPA Software Center… $ uname -a Linux peluche 3.2.0-56-generic #86~lp1246664 SMP Mon Nov 4 11:21:05 UTC 2013 i686 i686 i386 GNU/Linux $ $ cat /proc/swaps Filename Type Size Used Priority /dev/zram0 partition 772040 0 5 /dev/zram1 partition 772040 0 5 /dev/sdb5 partition 3174396 0 -1 $ Before meeting with the buffer I/O error I used to change the default values for the size of the swap devices (lower the size to 1/4) and setup the swappiness to 0, but for the test I do leave the default values unchanged. I will come back later to add information according to the results I will get. Now I will start an additional heavy load by starting Ubuntu Builder and build a custom ISO with your newer kernel and reinstall zram-config to it. (At least to test the behavior while 'heavy duty' is being done). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1246664 Title: "Buffer I/O error on device zram0, logical block 515067" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1246664/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
