Title:
  prio-inv from ubuntu_stress_smoke_test hangs on GCP g1-small with 5.4
  / 4.15 / 4.4 lowlatency

Status in ubuntu-kernel-tests:
  Fix Released

Bug description:
  Issue found exclusively on GCP "g1-small" instance with the following kernels:
    * X 4.4.0-252.286 lowlatency (s2024.02.05 cycle)
    * X-hwe 4.15.0-223.235~16.04.1 lowlatency (s2024.02.05 cycle)
    * F 5.4.0-175.195 lowlatency (2024.03.04 cycle)

  It looks like it's not 100% reproducible as it has passed with
    * B-lowlatency 4.15.0-223.235 (s2024.02.05 cycle)
    * F 5.4.0-174.193 lowlatency (s2024.02.05 cycle)

  When this happens, test will be interrupted:
