Hi,

Following up with the test results:

Unit/integration tests:
https://github.com/apache/kafka/actions/runs/25053481746

System tests:
Core: https://drive.google.com/file/d/1k7Vblxai4n1hV6mPlJ4O_Zp5zJx3OYuC/view?usp=sharing
1 failure: test_rate_device_name=eth0_latency_ms=50_metadata_quorum=COMBINED_KRAFT_rate_limit_kbit=1000000_task_name=rate-1000-latency-50
kafkatest.tests.core.network_degrade_test
The test consistently fails in my environment

Non Core: https://drive.google.com/file/d/16Fg7IcKOl5l3sbfcLjD08Wd6yWEP2ofx/view?usp=sharing
1 failure: test_replica_lags_metadata_quorum=ISOLATED_KRAFT
kafkatest.tests.tools.replica_verification_test
The test is flaky, it passed in a rerun.

Thanks,
Mickael
