[Bug 1246664] Re: Buffer I/O error on device zram0, logical block 515067
Hi Damian, According to you output zram does not appear to be loaded, if it was we would see a zram device, ie: /dev/zram0, /dev/zram1 (if your machine has two processors, dual core, core duo, or hyperthreading). You can remove the 3 following files: /var/crash/zram-config.0.crash /var/crash/zram-config.0.upload /var/crash/zram-config.0.uploaded and you can uninstall all the previous kernels and headers which have been installed in your system before the 3.2.0-58. If you fear something works less well, you could keep the two last sets, linux-image and linux-headers, ie 3.2.0-58 and 3.2.0-56. You can use Synaptic to do that (filter with search name linux then, search name headers, then click on the top of the first row to gather the said names which a related to installed packages). You will gain more or less 120 MB for each old kernel + headers removed. -- 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

Hi, I had not found this bug n° #1246664 when seeking for bugs related to zram, and I posted my own, however Oibaf found it and told me: https://bugs.launchpad.net/ubuntu/+source/zram-config/+bug/1247496 linux kernel 3.2.0-55 generic is the one used. I would be very glad to get a 3.2.0-55 generic patched. I would like to know what is the fix that you use? Oibaf also told me About the stop you should open a new bug. : do you confirm the Stop line should not be missing in the /etc/init/zram- config.conf file, if so that it is not what triggers problems, and therefore that I should open a new bug for it?

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.

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.

Thank of reporting this -- it looks like the fix for the Precise kernels is actually missing. I've uploaded a test kernel containing the fix (I've uploaded only a -pae kernel since this seems to be what Damien is using, but I can upload others if required). Basically this is a 3.2.0-56.86 kernel with a backport of commit: 75c7caf zram: allow request end to coincide with disksize Here's the link: http://people.canonical.com/~henrix/lp1246664/ Please let me know if this fixes the problem for you. -- 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

Could you explain, how to install it? When I click on any of those packages, I end up in Ubuntu Software Center with an error message and no install button. Are you sure they are fine? ** Attachment added: screenshot https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1246664/+attachment/3898066/+files/Screenshot%20from%202013-11-01%2023%3A24%3A50.png -- 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

** Description changed: This is a duplicate of #1217189, but for some reason neither @oibaf nor me can reopen it. It is in fix released state, but the problem is at most partially solved. It seems that the bug no longer causes lockups (described in another bug: #1215513), but is still present (as I get error messages on boot screen and after $ dmesg | grep zram). - If someone have enough privileges to reopen 1217189 for linux (ubuntu) + If someone has enough privileges to reopen 1217189 for linux (ubuntu) (I don't know about raring, but no one complains, so it is probably ok), and remove this bug (maybe merging this message to the comments in 1217189), I would be really grateful. Ubuntu 12.04.3 LTS Kernel Linux 3.2.0-56-generic-pae (the problem was first observed in 53 and since 54 there are no lockups). -- 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-lts-raring/+bug/1246664/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
