I was incorrect, it's actually a racy read on /proc/bus/pci/0000:00/00.0 that's causing a hang:
sudo cat /proc/bus/pci/0000\: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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1839461 Title: sysfs / procfs from ubuntu_stress_smoke_test failed on D-AWS ARM64 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1839461/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
