[Bug 164904] Re: stray mappings left behind by xfs make xen kernels crash.
The Ubuntu Kernel Team is planning to move to the 2.6.27 kernel for the upcoming Intrepid Ibex 8.10 release. As a result, the kernel team would appreciate it if you could please test this newer 2.6.27 Ubuntu kernel. There are one of two ways you should be able to test: 1) If you are comfortable installing packages on your own, the linux- image-2.6.27-* package is currently available for you to install and test. --or-- 2) The upcoming Alpha5 for Intrepid Ibex 8.10 will contain this newer 2.6.27 Ubuntu kernel. Alpha5 is set to be released Thursday Sept 4. Please watch http://www.ubuntu.com/testing for Alpha5 to be announced. You should then be able to test via a LiveCD. Please let us know immediately if this newer 2.6.27 kernel resolves the bug reported here or if the issue remains. More importantly, please open a new bug report for each new bug/regression introduced by the 2.6.27 kernel and tag the bug report with 'linux-2.6.27'. Also, please specifically note if the issue does or does not appear in the 2.6.26 kernel. Thanks again, we really appreicate your help and feedback. ** Tags added: cft-2.6.27 -- stray mappings left behind by xfs make xen kernels crash. https://bugs.launchpad.net/bugs/164904 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 164904] Re: stray mappings left behind by xfs make xen kernels crash.
I tried this patch but it didn't work for me. I reinstalled the system with ext3 and also migrated all the domUs to ext3. But again the system keeps crashing like you can see in the attached log-file. Could it be that there is some similar problem with ext3 or do I have some totally different issues? ** Attachment added: xen-error.txt http://launchpadlibrarian.net/11374574/xen-error.txt -- stray mappings left behind by xfs make xen kernels crash. https://bugs.launchpad.net/bugs/164904 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I'm using the Debian-Etch-Xen-Kernel again (2.6.18) - it works rock solid (uptime of more than 100 days etc.) compared to the Ubuntu-Xen- Kernel which crashed for me almost every day, even without ext3. -- stray mappings left behind by xfs make xen kernels crash. https://bugs.launchpad.net/bugs/164904 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I discovered 3 frozen systems in the last two days, all in combination with I/O errors. The xfs_repair discovered bad inodes.

[Bug 164904] Re: stray mappings left behind by xfs make xen kernels crash.
Reassigning to the kernel team to request a xen image for 2.6.24 be made. Also, I'l going to close the Gutsy task against the 'linux' package. The reason is that Gutsy is a valid target for linux- source-2.6.22. However, the 'linux' package is meant for Hardy kernels and later so having a Gutsy task for it doesn't make sense.

[Bug 164904] Re: stray mappings left behind by xfs make xen kernels crash.
Copy of my mail to kernel-team: Show Details Hi, after reading through https://wiki.ubuntu.com/StableReleaseUpdates I think that bug 164904 is appropriate for gutsy. Problem: - XFS delays vunmap and leaves stale mappings. This is considered wrong even in normal kernel. But as Xen uses those mappings memory corruption can occur Why I think its appropriate for gutsy - It causes, sometimes silent, data-corruption and crashes - Hard to diagnose as the backtraces are quite random - Obviously correct fix, as the fix is the fallback currently used in tight memory conditions. - Patch is applied upstream Any other Information needed?

[Bug 164904] Re: stray mappings left behind by xfs make xen kernels crash.
H Leann, Thanks for approving. But the 2.6.24 kernel doesnt help me, does it? I think the problem is cosmetic for -generic kernels as far as I read/understood the code, ie. only relevant for xen kernels (and there is no -xen flavour of 2.6.24 yet). Secondly, I dont want to use 2.6.24 on a production machine...

As additional info, here is the git commit: commit 7f015072348a14f16d548be557ee58c5c55df0aa Author: Jeremy Fitzhardinge [EMAIL PROTECTED] Date: Wed Oct 17 13:55:03 2007 +1000 [XFS] eagerly remove vmap mappings to avoid upsetting Xen XFS leaves stray mappings around when it vmaps memory to make it virtually contigious. This upsets Xen if one of those pages is being recycled into a pagetable, since it finds an extra writable mapping of the page. This patch solves the problem in a brute force way, by making XFS always eagerly unmap its mappings.

Hi Andres, I went ahead and approved with for a Gutsy SRU. Also, I just wanted to let you know this patch is already merged in the Hardy Heron kernel that was released for testing, linux-image-2.6.24-1-generic.
