Tagging this bug as verified for Precise.

I observe the same kernel bug on Ubuntu 11.10 (oneiric) with kernel 3.0.0-19-generic, see the attached syslog. Interestingly, it's not there in the vanilla install of Ubuntu 11.10 with kernel 3.0.0-12-generic (tested by booting an older kernel from grub). This issue manifests itself when I log in using an LDAP user with home on an NFS mount. Any chance of fixing it on Ubuntu 11.10? ** Attachment added: extract /var/log/syslog with the bug description https://bugs.launchpad.net/ubuntu/+source/linux/+bug/974664/+attachment/3140100/+files/oneiric_kernel_bug_syslog -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/974664 Title: Kernel Oops - BUG: unable to handle kernel paging request at ffb8; RIP: 0010:[a05a5839] [a05a5839] nfs_have_delegation+0x9/0x40 [nfs] To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/974664/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: #10, Luis, thanks for your efforts on this. By running http://people.canonical.com/~henrix/lp974664v2, the Oops is indeed resolved and the rate limiting is definitely reducing the numbers of messages produced but none the less there are many many dozens of messages produced still -- just like with the mainline kernel infact.

I have ping'ed upstreams about the issue and two new patches (not yet upstream) have been provided.

Ian: Thanks for testing the kernel. Apparently, these messages are harmless and the mainline kernel has already a ratelimiting patch for this. I have backported the ratelimiting commit (96dcadc2fdd111dca90d559f189a30c65394451a) on top of the kernel you tested and uploaded it here: http://people.canonical.com/~henrix/lp974664v2/ Please let me know if this new kernel fixes it. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/974664 Title: Kernel Oops - BUG: unable to handle kernel paging request at ffb8; RIP: 0010:[a05a5839] [a05a5839] nfs_have_delegation+0x9/0x40 [nfs] To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/974664/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Re: #10, Luis, thanks for your efforts on this. By running http://people.canonical.com/~henrix/lp974664v2, the Oops is indeed resolved and the rate limiting is definitely reducing the numbers of messages produced but none the less there are many many dozens of messages produced still -- just like with the mainline kernel infact. I assume the mainline kernel also had the rate limiting patch applied. I'm not entirely sure about the harmless nature of the messages however. My perception is that logging in is somewhat slower -- this may be down to the beta nature of the release at present however what I am observing, even after logon of the user has completed is a high level of network activity. Running a packet trace and a wireshark dump of this activity, it seems that the activity is down to NFS and it seems (see screenshot attached) to be stuck in somewhat of a loop -- specifically continually getting an error when trying to lock the file (each time the same file). I wonder if the slowness has the same root cause (the shere number of failed retries -- looking at the packet trace it seems, if I'm not mistaken, there's about 1000 per second of these!) I observe the file being processed is user.keystore and in my case, the prior oops was triggered by gnome-keyring-d so I can't help feeling these issues are related. However I will admit I'm no expert on NFS so I could be seeing ghosts :-) Let me know if there is any information I can provide that might help. ** Attachment added: Packet capture https://bugs.launchpad.net/ubuntu/+source/linux/+bug/974664/+attachment/3085980/+files/Screenshot%20from%202012-04-17%2021%3A55%3A23.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/974664 Title: Kernel Oops - BUG: unable to handle kernel paging request at ffb8; RIP: 0010:[a05a5839] [a05a5839] nfs_have_delegation+0x9/0x40 [nfs] To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/974664/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ian, thanks again for testing and helping triagging this bug. When I said harmless (and I'm far from being an expert on NFS as well!) I was not aware that the flood of messages being logged would be kept that high. Obviously, logging such a huge amount of messages will at least impact the performance. My comment referred to the fact that the log was actually on an error path that would be retried again.

This problem is reproduced by logging into Ubuntu with a user's home directory mounted over NFS... though only if the server is also running 12.04.

Actually, my server is Ubuntu 11.10, so if this is an NFS related issue, it's not confined to 12.04.

I'm seeing the same OOps -- again Logging into a 12.04 client system with autofs5, LDAP, kerberos authenticated nfs4 mounts.

rvaliant, thank you for reporting this bug and helping make Ubuntu better. Please answer these questions: * Is this reproducible? * If so, what specific steps should we take to recreate this bug? * Could you also please test the latest upstream kernel available? It will allow additional upstream developers to examine the issue. Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Once you've tested the upstream kernel, please remove the 'needs-upstream-testing' tag. 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. Please let us know your results.
