Public bug reported: I encountered an kernel oops running 3.11.0-7-generic #13-Ubuntu SMP Tue Sep 10 20:55:38 UTC 2013 x86_64 GNU/Linux under Debian Squeeze 6.0.7 amd64 on an Opteron barebone.
This server is an NFS client using cachefilesd. The NFS server is Debian Squeeze 6.0.7 amd64 running 3.2.0-0.bpo.4-amd64 #1 SMP Debian 3.2.46-1~bpo60+1 x86_64 GNU/Linux and nfs-kernel-server on an Opteron barebone. No kerberos is in use. To get things up and running for 700+ user ids, i configured the following on the client, using trial and error, to have the correct user ids on the NFS mount: echo N > /sys/module/nfs/parameters/nfs4_disable_idmapping kernel.keys.root_maxbytes = 100000 kernel.keys.root_maxkeys = 1000 kernel.keys.maxbytes = 100000 kernel.keys.maxkeys = 1000 I was capturing the trace via an SSH session using tail -f so some information might be missing :-/ (attached) Thanks, Raoul ** Affects: linux (Ubuntu) Importance: Undecided Status: New ** Attachment added: "oops.txt" https://bugs.launchpad.net/bugs/1225490/+attachment/3821094/+files/oops.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1225490 Title: BUG: unable to handle kernel paging request at 0000000100000000 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1225490/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
