[Kernel-packages] [Bug 1839461] Re: sysfs / procfs from ubuntu_stress_smoke_test failed on D-AWS ARM64
I was incorrect, it's actually a racy read on /proc/bus/pci/:00/00.0 that's causing a hang: sudo cat /proc/bus/pci/\:00/00.0 ..takes a few seconds.. with stress-ng we have a multi-threaded open/read/close on this file with random read sizes, this seems to cause the machine to hang and reboot a while later. Reduced this down to a single threaded read and the same issue occurs. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-aws in Ubuntu. https://bugs.launchpad.net/bugs/1839461 Title: sysfs / procfs from ubuntu_stress_smoke_test failed on D-AWS ARM64 Status in ubuntu-kernel-tests: New Status in linux-aws package in Ubuntu: New Status in linux-aws source package in Disco: New Bug description: Issue found on arm64 node with D-AWS kernel sysfs failed on: a1.2xlarge / a1.large procfs failed on: a1.2xlarge / a1.medium sysfs failure: sysfs FAILED stress-ng: debug: [16876] 8 processors online, 8 processors configured stress-ng: info: [16876] dispatching hogs: 4 sysfs stress-ng: debug: [16876] cache allocate: reducing cache level from L3 (too high) to L2 stress-ng: debug: [16876] cache allocate: default cache size: 2048K stress-ng: debug: [16876] starting stressors stress-ng: debug: [16877] stress-ng-sysfs: started [16877] (instance 0) stress-ng: debug: [16878] stress-ng-sysfs: started [16878] (instance 1) stress-ng: debug: [16876] 4 stressors spawned stress-ng: debug: [16879] stress-ng-sysfs: started [16879] (instance 2) stress-ng: debug: [16880] stress-ng-sysfs: started [16880] (instance 3) stress-ng: error: [16877] stress-ng-sysfs: A SIGSEGV occurred while exercising /sys/power/pm_print_times, aborting stress-ng: debug: [16877] stress-ng-sysfs: exited [16877] (instance 0) stress-ng: error: [16876] process 16877 (stress-ng-sysfs) terminated with an error, exit status=1 (stress-ng core failure) stress-ng: debug: [16876] process [16877] terminated stress-ng: error: [16878] stress-ng-sysfs: A SIGSEGV occurred while exercising /sys/kernel/irq/1/name, aborting stress-ng: debug: [16878] stress-ng-sysfs: exited [16878] (instance 1) stress-ng: error: [16876] process 16878 (stress-ng-sysfs) terminated with an error, exit status=1 (stress-ng core failure) stress-ng: debug: [16876] process [16878] terminated stress-ng: debug: [16879] stress-ng-sysfs: exited [16879] (instance 2) stress-ng: debug: [16876] process [16879] terminated stress-ng: debug: [16880] stress-ng-sysfs: exited [16880] (instance 3) stress-ng: debug: [16876] process [16880] terminated stress-ng: info: [16876] unsuccessful run completed in 5.04s procfs failure: procfs FAILED stress-ng: debug: [27728] 8 processors online, 8 processors configured stress-ng: info: [27728] dispatching hogs: 4 procfs stress-ng: debug: [27728] cache allocate: reducing cache level from L3 (too high) to L2 stress-ng: debug: [27728] cache allocate: default cache size: 2048K stress-ng: debug: [27728] starting stressors stress-ng: debug: [27729] stress-ng-procfs: started [27729] (instance 0) stress-ng: debug: [27730] stress-ng-procfs: started [27730] (instance 1) stress-ng: debug: [27728] 4 stressors spawned stress-ng: debug: [27731] stress-ng-procfs: started [27731] (instance 2) stress-ng: debug: [27732] stress-ng-procfs: started [27732] (instance 3) *** stack smashing detected ***: terminated stress-ng: debug: [27730] stress-ng-procfs: exited [27730] (instance 1) stress-ng: debug: [27729] stress-ng-procfs: exited [27729] (instance 0) stress-ng: debug: [27728] process [27729] terminated stress-ng: debug: [27728] process [27730] terminated stress-ng: debug: [27728] process [27731] (stress-ng-procfs) terminated on signal: 6 (Aborted) stress-ng: debug: [27728] process [27731] terminated stress-ng: debug: [27732] stress-ng-procfs: exited [27732] (instance 3) stress-ng: debug: [27728] process [27732] terminated stress-ng: info: [27728] unsuccessful run completed in 5.00s ProblemType: Bug DistroRelease: Ubuntu 19.04 Package: linux-image-5.0.0-1011-aws 5.0.0-1011.12 ProcVersionSignature: User Name 5.0.0-1011.12-aws 5.0.15 Uname: Linux 5.0.0-1011-aws aarch64 ApportVersion: 2.20.10-0ubuntu27.1 Architecture: arm64 Date: Thu Aug 8 11:03:32 2019 Ec2AMI: ami-0ac1a3bc4f5c85238 Ec2AMIManifest: (unknown) Ec2AvailabilityZone: us-west-2c Ec2InstanceType: a1.medium Ec2Kernel: unavailable Ec2Ramdisk: unavailable SourcePackage: linux-aws UpgradeStatus: No upgrade log present (probably fresh install) To manage
