The kernel panic itself locks up the system instantly and therefore no logging to disk happens of that error. Therefore, see the attached screenshot of the qemu screen after the crash.

After notifying the hosting company the machine was migrated to a different physical host which didn't fix the problem. A complete reinstall of Ubuntu 16.04 also didn't fix anything. Therefore, I suspect some sort of bug in the kernel and not a hardware fault or a corrupted install. /proc/version_signature: Ubuntu 4.4.0-47.68-generic 4.4.24 ProblemType: Bug DistroRelease: Ubuntu 16.04 Package: linux-image-4.4.0-47-generic 4.4.0-47.68 ProcVersionSignature: Ubuntu 4.4.0-47.68-generic 4.4.24 Uname: Linux 4.4.0-47-generic x86_64 AlsaDevices: total 0 crw-rw---- 1 root audio 116, 1 Nov 21 12:51 seq crw-rw---- 1 root audio 116, 33 Nov 21 12:51 timer AplayDevices: Error: [Errno 2] No such file or directory: 'aplay' ApportVersion: 2.20.1-0ubuntu2.1 Architecture: amd64 ArecordDevices: Error: [Errno 2] No such file or directory: 'arecord' AudioDevicesInUse: Error: [Errno 2] No such file or directory: 'fuser' Date: Mon Nov 21 12:57:11 2016 HibernationDevice: RESUME=UUID=704a373a-9754-4c59-bff2-001601f1c0bf IwConfig: Error: [Errno 2] No such file or directory: 'iwconfig' 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: Hetzner vServer PciMultimedia: ProcEnviron: TERM=xterm-256color PATH=(custom, no user) XDG_RUNTIME_DIR=<set> LANG=en_US.UTF-8 SHELL=/bin/bash ProcFB: ProcKernelCmdLine: BOOT_IMAGE=/vmlinuz-4.4.0-47-generic root=UUID=fc92f1ac-ee98-4991-8a92-93451bd36d56 ro nomodeset elevator=noop net.ifnames=0 RelatedPackageVersions: linux-restricted-modules-4.4.0-47-generic N/A linux-backports-modules-4.4.0-47-generic N/A linux-firmware 1.157.4 RfKill: Error: [Errno 2] No such file or directory: 'rfkill' SourcePackage: linux UpgradeStatus: No upgrade log present (probably fresh install) dmi.bios.date: 04/01/2014 dmi.bios.vendor: SeaBIOS dmi.bios.version: 1.8.2 dmi.chassis.type: 1 dmi.chassis.vendor: QEMU dmi.chassis.version: pc-i440fx-2.6 dmi.modalias: dmi:bvnSeaBIOS:bvr1.8.2:bd04/01/2014:svnHetzner:pnvServer:pvr2:cvnQEMU:ct1:cvrpc-i440fx-2.6: dmi.product.name: vServer dmi.product.version: 2 dmi.sys.vendor: Hetzner To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1643533/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
