I pushed the patches here:
https://gitlab.com/anisinha/qemu/-/commits/disable-smilatency
and ran the pipeline. It passed
https://gitlab.com/anisinha/qemu/-/jobs/5878585312

and the smilatency test was not run:
https://anisinha.gitlab.io/-/qemu/-/jobs/5878585312/artifacts/build/tests/results/latest/test-results/01-tests_avocado_acpi-bits.py_AcpiBitsTest.test_acpi_smbios_bits/debug.log

Not sure what we can do to have some confidence that disabling the
test got rid of the flakiness. I can send out those two patches in the
list.
