Bug Description
The dev stressor from ubuntu_
With further investigation, this issue can be reproduced with a VM on a bare-metal. When this happens the VM will be terminated. (Bare-metal can pass with this test)
It's 100% reproducible with the following steps:
# On a bare-metal running with Noble
sudo apt install uvtool build-essential -y
sudo uvt-simplestrea
SSH_KEY=
ssh-keygen -f $SSH_KEY -t rsa -N ''
sudo -u ubuntu uvt-kvm create oem610 release=noble arch=amd64 --memory 2048
sleep 60
ssh -o StrictHostKeyCh
# Inside the VM
sudo apt-add-repository ppa:canonical-
sudo apt install kernel-
sudo reboot
sleep 60
ssh -o StrictHostKeyCh
git clone https:/
cd stress-ng; make
sudo ./stress-ng -v -t 5 --dev 4 --dev-ops 3000 --ignite-cpu --syslog --verbose --verify --oomable
# VM will be terminated here, you will have to restart it.
Issue reported upstream: https:/
From Colin's investigation it looks like a kernel issue
This issue can be reproduced with mainline kernel v6.10-rc4 (AMD64 debs are not available for v6.10-rc6)
