** Description changed: I had a kernel problem with one of my high availability VMs. This was not the first occurence of the problem, it seems to appear every now and then. The VM froze because of the Kernel bug appended as a text file. I had to hard reset it. I am running Ubuntu 14.04.2 Kernel 3.16.0-34-generic with libapache2-mod-apparmor 2.8.95~2430-0ubuntu5.1 and apache 2.4.7-1ubuntu4.4 (mpm_prefork). Unfortunately I am unable to reproduce the bug at will. This is a serious problem for high availability VMs. Looking at the trace, I assume this is a bug in AppArmor. + --- + AlsaDevices: + total 0 + crw-rw---- 1 root audio 116, 1 May 15 14:13 seq + crw-rw---- 1 root audio 116, 33 May 15 14:13 timer + AplayDevices: Error: [Errno 2] No such file or directory + ApportVersion: 2.14.1-0ubuntu3.10 + Architecture: amd64 + ArecordDevices: Error: [Errno 2] No such file or directory + AudioDevicesInUse: Error: command ['fuser', '-v', '/dev/snd/seq', '/dev/snd/timer'] failed with exit code 1: + CRDA: Error: [Errno 2] No such file or directory + DistroRelease: Ubuntu 14.04 + HibernationDevice: RESUME=UUID=69e1aff7-c3d1-4bf4-8685-bd3fc2942f60 + InstallationDate: Installed on 2015-03-25 (61 days ago) + InstallationMedia: Ubuntu-Server 14.04.2 LTS "Trusty Tahr" - Release amd64 (20150218.1) + IwConfig: + eth0 no wireless extensions. + + lo no wireless extensions. + Lsusb: + Bus 001 Device 002: ID 0627:0001 Adomax Technology Co., Ltd + Bus 001 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub + MachineType: QEMU Standard PC (i440FX + PIIX, 1996) + Package: linux (not installed) + PciMultimedia: + + ProcEnviron: + LANGUAGE=en_US:en + TERM=xterm + PATH=(custom, no user) + LANG=en_US.UTF-8 + SHELL=/bin/bash + ProcFB: 0 cirrusdrmfb + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-37-generic root=UUID=fea3075f-a9a3-414b-992a-b812d86cd04e ro + ProcVersionSignature: Ubuntu 3.16.0-37.51~14.04.1-generic 3.16.7-ckt9 + RelatedPackageVersions: + linux-restricted-modules-3.16.0-37-generic N/A + linux-backports-modules-3.16.0-37-generic N/A + linux-firmware 1.127.11 + RfKill: Error: [Errno 2] No such file or directory + Tags: trusty + Uname: Linux 3.16.0-37-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: + + WifiSyslog: + + _MarkForUpload: True + dmi.bios.date: 04/01/2014 + dmi.bios.vendor: SeaBIOS + dmi.bios.version: rel-1.7.5.1-0-g8936dbb-20141113_115728-nilsson.home.kraxel.org + dmi.chassis.type: 1 + dmi.chassis.vendor: QEMU + dmi.chassis.version: pc-i440fx-2.2 + dmi.modalias: dmi:bvnSeaBIOS:bvrrel-1.7.5.1-0-g8936dbb-20141113_115728-nilsson.home.kraxel.org:bd04/01/2014:svnQEMU:pnStandardPC(i440FX+PIIX,1996):pvrpc-i440fx-2.2:cvnQEMU:ct1:cvrpc-i440fx-2.2: + dmi.product.name: Standard PC (i440FX + PIIX, 1996) + dmi.product.version: pc-i440fx-2.2 + dmi.sys.vendor: QEMU ** Attachment added: "BootDmesg.txt" https://bugs.launchpad.net/bugs/1448912/+attachment/4404581/+files/BootDmesg.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1448912 Title: BUG: unable to handle kernel NULL pointer dereference (aa_label_merge) To manage notifications about this bug go to: https://bugs.launchpad.net/apparmor/+bug/1448912/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
