lowlatency Status in ubuntu-kernel-tests: New 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: START ubuntu_stress_smoke_test.prio-inv ubuntu_stress_smoke_test.prio-inv
