I think these failures are all due to https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/arch/arm64/kernel/perf_callchain.c?id=33c222aeda14596ca5b9a1a3002858c6c3565ddd. This causes unwinding to show only one level in certain cases, so this test (which checks for multiple levels recursive;recursive;recursive;... fails.
