[Bug 515937] Re: Filesystems end up remounted read-only
Hello, I experience that behaviour about once or twice a day with one of my three 64bit machines (always the same). The other two are unaffected, although I run the same Ubuntu 12.04.1 LTS on all machines. The affected one is an i7-2700K CPU @ 3.50GHz. However, among the unaffected is an i7-2670QM CPU @ 2.20GHz. The SMART status of the HD is ok. If thus bus error happens, I cannot even do a sudo shutdown but have to do a hard reset, which is a quite unsatisfying situation. al -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/515937 Title: Filesystems end up remounted read-only To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/515937/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 515937] Re: Filesystems end up remounted read-only
It seems this bug is related to https://bugs.launchpad.net/ubuntu/+source/linux/+bug/346691, which seems to randomly affect different 64bit kernel releases and not others. This would explain why the error report on the Ubuntu forums about this dated back to 2008 and such. If the developers looked for a patch pattern within the affected kernels, that would likely be a good start. I think the reason this recently started affecting me a lot might be due to the latest kernel (2.6.32-22). I did not have the issues as all with kernel 2.6.32-21 as GUmeR reports, so reverting to that is the best bet for avoiding this issue for now.

Here is thread on Ubuntu forums about this bug: http://ubuntuforums.org/showthread.php?t=1475124. Here is bug report on kernel bugzilla https://bugzilla.kernel.org/show_bug.cgi?id=16006. Looks like it was fixed in newer kernel. Didin't check it though ** Bug watch added: Linux Kernel Bug Tracker #16006 http://bugzilla.kernel.org/show_bug.cgi?id=16006 -- Filesystems end up remounted read-only https://bugs.launchpad.net/bugs/515937 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
[Bug 515937] Re: Filesystems end up remounted read-only
This does sound possible - is this commit in a mainline Ubuntu kernel, and if so, which? Quote from https://bugzilla.kernel.org/show_bug.cgi?id=16006 Comment #4 From Tejun Heo 2010-05-19 14:40:31 --- FLUSH_EXT timed out which shouldn't happen but can. libata as of 2.6.32 doesn't retry after any FLUSH failure and just returns the error to upper layer leading to fs ro remounting the device. The reason for the behavior is that FLUSH failure often indicates (abort by device always does) data loss so continuing RW operation is likely to cause massive filesystem corruption. As the behavior caused some spurious failures like this, EH was updated to distinguish between various FLUSH failure modes and retry unless it's certain that the device aborted it. So, in short, please upgrade to newer kernel or tell your distro to backport the update.

I have the same issue as well, except I have an ASUS laptop running 64bit Ubuntu with an ext4 partition.

[Bug 515937] Re: Filesystems end up remounted read-only
The kernel version I am using at the moment is the standard Ubuntu build of 2.6.32.22. This error occurs about once a day during normal use, which for me includes running a word processor, sometimes a torrent program or sometimes not, empathy and other standard Ubuntu desktop applications. It most commonly happens when I am watching a video, which involves lots of constant data reading and likely increases the chance of meeting the circumstances which cause this bug to occur. I also replaced the 'errors=remount-readonly' in the fstab entry for my root partition with 'defaults' several occurrences of this issue ago and tune2fs says the error mode should be to continue, but the remounting read-only still happens which definitely makes it seem like a deep- rooted kernel issue. I would love to see this resolved soon, so please let me know if I can give any further data to assist in its resolution. -- Filesystems end up remounted read-only https://bugs.launchpad.net/bugs/515937 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

I have exactly the same issue, also Lenovo laptop :/ Did you open a bug on kernel bugzilla? If yes, what is bug number?

This looks similar to an issue followed on this linux-kernel thread: http://marc.info/?t=12379584391r=1w=2 Please open a bug in the kernel bugzilla (http://bugzilla.kernel.org) to track this issue.
