Bug description:
  The pty07 test from ubuntu_ltp will cause test interrupt with Noble
  OEM 6.10 VM on openstack since 6.10.0-1003.3

  This issue can be reproduced with a VM on a bare-metal. When this
  happens the VM will be terminated. (Test passed on a Bare-metal with
  6.10.0-1005-oem).

  Test log:
  <<<test_start>>>
  tag=pty07 stime=1719989938
  cmdline="pty07"
  contacts=""
  analysis=exit
  <<<test_output>>>

  tst_test.c:1617: TINFO: Timeout per run is 0h 03m 00s

  Steps:
  # On a bare-metal running with Noble
  sudo apt install uvtool build-essential -y
  sudo uvt-simplestreams-libvirt sync --source http://cloud-images.ubuntu.com/daily release=noble arch=amd64
  SSH_KEY="$HOME/.ssh/id_rsa"
  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 StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o LogLevel=quiet -i .ssh/id_rsa ubuntu@`sudo uvt-kvm ip oem610`
  # Inside the VM
  sudo apt-add-repository ppa:canonical-kernel-team/ubuntu/proposed -y
  sudo apt install kernel-testing--linux-oem-6.10--full--oem -y
  sudo reboot
  sleep 60
  ssh -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -o LogLevel=quiet -i .ssh/id_rsa ubuntu@`sudo uvt-kvm ip oem610`
