This is not a regression, as it's the first time we test J-AWS-6.5. And
for J-oem-6.5 this test exists since 6.5.0-1002.2, but it will be
skipped on openstack VM. Because of an outage in Intel lab, we did not
test this kernel with bare-metal until recent cycle with 6.5.0-1005.5
(1004 this test was aborted due to deployment failure)
