The below three testcases are failing on IBM Power Architecture(ppc64le). This only started happening during the latest merges, we are also seeing this on AWS with 4.21.

[sig-arch][Late][Jira:"kube-apiserver"] all registered tls artifacts must have no metadata violation regressions [Suite:openshift/conformance/parallel]
[sig-arch][Late][Jira:"kube-apiserver"] all tls artifacts must be registered [Suite:openshift/conformance/parallel]
[sig-arch][Late][Jira:"kube-apiserver"] collect certificate data [Suite:openshift/conformance/parallel]

    Continuously failing on normal cluster, IPSec encryption enabled cluster, VLAN configured cluster.

    1. git clone -b release-4.21 https://github.com/openshift/origin.git     
    2. cd origin
    3. make build
    4. ./openshift-tests run -f tests.txt -o output.txt
    

The testcases are failing
Blocking test failures:        
* [sig-arch][Late][Jira:"kube-apiserver"] all registered tls artifacts must have no metadata violation regressions [Suite:openshift/conformance/parallel]
* [sig-arch][Late][Jira:"kube-apiserver"] all tls artifacts must be registered [Suite:openshift/conformance/parallel]
* [sig-arch][Late][Jira:"kube-apiserver"] collect certificate data [Suite:openshift/conformance/parallel]

    The testcases should pass.

Ginkgo detected an issue with your spec structure
github.com/openshift/origin/test/extended/util/client.go:183
  It looks like you are trying to add a [BeforeEach] node
  to the Ginkgo spec tree in a leaf node after the specs started running.

  To enable randomization and parallelization Ginkgo requires the spec tree
  to be fully constructed up front.  In practice, this means that you can
  only create nodes like [BeforeEach] at the top-level or within the
  body of a Describe, Context, or When.
