--Shyam -----Original Message----- From: boun...@canonical.com [mailto:boun...@canonical.com] On Behalf Of Joseph Salisbury Sent: Friday, December 16, 2011 8:07 PM To: sh...@zadarastorage.com Subject: [Bug 905219] Re: Linux Kernel crash in Netfilter both in Natty (2.6.38-8-server) and oneiric(3.0.0-13-server) kernels Hi Shyam, Would it be possible for you to test the latest upstream kernel? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . If possible, please test the latest v3.2-rcN kernel (Not a kernel in the daily directory). Once you've tested the upstream kernel, please remove the 'needs-upstream- testing' tag(Only that one tag, please leave the other tags). This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the 'needs-upstream- testing' text. If this bug is fixed by the mainline kernel, please add the following tag 'kernel-fixed-upstream-KERNEL-VERSION'. For example, if kernel version 3.2-rc1 fixed and issue, the tag would be: 'kernel-fixed- upstream-v3.2-rc1'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. If you are unable to test the mainline kernel, for example it will not boot, please add the tag: 'kernel-unable-to-test-upstream'. Thanks in advance. ** Changed in: linux (Ubuntu) Importance: Undecided => High ** Tags added: kernel-da-key needs-upstream-testing -- You received this bug notification because you are subscribed to the bug report. https://bugs.launchpad.net/bugs/905219 Title: Linux Kernel crash in Netfilter both in Natty (2.6.38-8-server) and oneiric(3.0.0-13-server) kernels Status in “linux” package in Ubuntu: Confirmed Bug description: On multiple servers on which we have Ubuntu versions installed we periodically hit this kernel panic. in netfilter flowpath The console freezes & the only way is to physically reboot the servers. We run KVM and few VM's on the physical servers. On the physical eth's bridges are created and TAP interfaces are setup into the bridges. These TAP interfaces are connected into KVM through libvirt (we primarily use openstack for the VM management). This problem happened in Natty 2.6.38-8-server version. After looking at the below links, we thought this could be a problem on 2.6.38-8-server kernel that is bundled along with Natty & decided to move to oneiric running 3.0 kernel. http://lkml.indiana.edu/hypermail/linux/kernel/1106.0/00755.html https://lkml.org/lkml/2011/6/1/754 http://www.spinics.net/lists/netfilter-devel/msg17239.html https://lkml.org/lkml/2011/2/3/147 However, this exact problem is repeating in oneiric kernels. We request you to pls look at this issue asap. I will be happy to provide you any additional information that you will need.
