Upon further investigation, the device mapper observation does not seem to be a hard line, as I was able to observe panics when stressing both dm-0 and nvme0n1 under different circumstances.
At the moment, it also seems like the specific part of stress_ng_test that is the culprit is the "stress-ng aiol stressor". When running only the "aiol" stressor in isolation on linux-image-6.8.0-11-generic-64k, the panic reliably happens in under 5 minutes. Currently investigating to see if any other stress_ng tests cause the same issue on this kernel version, or if it is only aiol. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2058557 Title: Kernel panic during checkbox stress_ng_test on Grace running noble 6.8 (arm64+largemem) kernel Status in linux package in Ubuntu: New Bug description: A kernel oops and panic occurred during 22.04 SoC certification on Gunyolk (Grace/Grace) with 6.8 kernel, arm64+largemem variant Steps to reproduce: Run (as root) the following commands: add-apt-repository -y ppa:checkbox-dev/stable apt-add-repository -y ppa:firmware-testing-team/ppa-fwts-stable apt update apt install -y canonical-certification-server /usr/lib/checkbox-provider-base/bin/stress_ng_test.py disk --device dm-0 --base-time 240 stress_ng_test caused a kernel panic after about 5 minutes. I have attached dmesg output from my reproducer to this report. Initially, this was identified via a panic during the above test, which was running as part of a run of certify-soc-22.04.
