apport information ** Tags added: apport-collected trusty uec-images
** Description changed: Over the past 3-ish weeks we've had 3 seperate HP Proliant DL380 Gen9 servers lock up with a similar looking cpu lockup bug. All 3 of these servers are nova-compute nodes in an OpenStack cluster, with a reasonable amount of load on them. The symptoms are the load shoots up into the hundreds, and ps stops returning. I've attached lspci -vnvn and 3 sets of syslog message traces that we grabbed on each of the 3 times it has crashed. $ cat /proc/version_signature Ubuntu 3.16.0-49.65~14.04.1-generic 3.16.7-ckt15 Please let us know if you need any further information. + --- + AlsaDevices: + total 0 + crw-rw---- 1 root audio 116, 1 Sep 29 06:47 seq + crw-rw---- 1 root audio 116, 33 Sep 29 06:47 timer + AplayDevices: Error: [Errno 2] No such file or directory + ApportVersion: 2.14.1-0ubuntu3.15 + 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=c2111986-9219-44f2-ad09-8d367ce8b30b + MachineType: HP ProLiant DL380 Gen9 + Package: linux (not installed) + PciMultimedia: + + ProcEnviron: + TERM=xterm + PATH=(custom, no user) + XDG_RUNTIME_DIR=<set> + LANG=en_US.UTF-8 + SHELL=/bin/bash + ProcFB: 0 EFI VGA + ProcKernelCmdLine: BOOT_IMAGE=/boot/vmlinuz-3.16.0-49-generic root=UUID=038cefb6-3559-4104-9754-5308497961f5 ro console=tty0 console=ttyS1,115200 BOOTIF=01-3c:a8:2a:23:f5:00 quiet + ProcVersionSignature: Ubuntu 3.16.0-49.65~14.04.1-generic 3.16.7-ckt15 + RelatedPackageVersions: + linux-restricted-modules-3.16.0-49-generic N/A + linux-backports-modules-3.16.0-49-generic N/A + linux-firmware 1.127.15 + RfKill: Error: [Errno 2] No such file or directory + Tags: trusty uec-images + Uname: Linux 3.16.0-49-generic x86_64 + UpgradeStatus: No upgrade log present (probably fresh install) + UserGroups: adm cdrom dialout libvirtd lpadmin plugdev sambashare sudo + _MarkForUpload: True + dmi.bios.date: 05/06/2015 + dmi.bios.vendor: HP + dmi.bios.version: P89 + dmi.chassis.type: 23 + dmi.chassis.vendor: HP + dmi.modalias: dmi:bvnHP:bvrP89:bd05/06/2015:svnHP:pnProLiantDL380Gen9:pvr:cvnHP:ct23:cvr: + dmi.product.name: ProLiant DL380 Gen9 + dmi.sys.vendor: HP ** Attachment added: "BootDmesg.txt" https://bugs.launchpad.net/bugs/1500739/+attachment/4479435/+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/1500739 Title: CPU lockup on HP Proliant DL380 Gen9 servers To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1500739/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
