This test is still failing for Eoan 5.3.0-43.36 on node kili, onibi. But surprisingly it has passed on node vought with the same kernel.

With Oracle Focal 5.4.0-1021.21
This is only failing on VM.Standard2.1, but passed on VM.Standard2.16

[Sean Feole (sfeole)]

This appears to just be a nuisance now, rather than a reliable test as it is consistently failing in clouds. Will take some time to break this down and figure out if we can fix the test.
