Describe the problem
We have disabled grunning for s390x through #95291 as patched Go runtime is not available. Recent commit 4c2d4c3 adds tests for ARM MacOS however it also gets executed on s390x.
On s390x, this fails with below error:
Test: TestRebalanceObjectiveManager
Error Trace: github.com/cockroachdb/cockroach/pkg/kv/kvserver/pkg/kv/kvserver/rebalance_objective_test.go:209
Error: Not equal:
expected: 1
actual : 0

Also , recent commit (408e227) to kvserver_test causing failure on s390x to TestMergeQueue/load-based-merging.
