Name of failing test

(command rocm-smi || true) && export VLLM_TEST_GROUP_NAME=mi355_1-language-models-tests-standard && export VLLM_ALLOW_DEPRECATED_BEAM_SEARCH=1 && cd /vllm-workspace/tests && pip freeze | grep -E 'torch' && pytest -v -s models/language -m 'core_model and (not slow_test)'

Basic information

  • Flaky test
  • Can reproduce locally
  • Caused by external libraries (e.g. bug in transformers)

🧪 Describe the failing test

  • Latest nightly date: 2026-04-22
  • Latest build(s): amd-ci #7880
  • Latest hardware status: mi355_1=fail

📝 History of failing test

  • Current streak start: 2026-04-16
  • First failure: Unknown

extent analysis

TL;DR

  • Investigate the mi355_1 hardware status and recent changes to identify the cause of the failing Language Models Tests.

Guidance

  • Review the test history and failure frequency to determine if the issue is intermittent or persistent.
  • Check the hardware status of mi355_1 for any errors or warnings that may indicate a hardware-related problem.
  • Examine the changes made in the latest build (#7791) to see if any updates or modifications could be causing the test failures.
  • Verify if the issue is specific to the mi355_1 hardware or if other AMD hardware is also experiencing failures.

Notes

  • The issue seems to be related to a specific hardware setup (mi355_1) and test group (Language Models Tests), so the solution may involve hardware-specific configurations or updates.
  • The break frequency and first failure in the 60-day window suggest that the issue may have started recently, so reviewing recent changes and updates is crucial.

Recommendation

  • Apply workaround: Investigate and address the mi355_1 hardware status and test failures to prevent further breakage, as the root cause is unclear and may require specific hardware or test adjustments.
