How reproducible:

Steps to Reproduce:

    1.Create a openshift sandbox cluster(4.16.x) having few node on s390x and others on x86.
    2.upgrade it to next recommended version.
    3.You will find the issue
    

Actual results:

We encountered an issue while upgrading our OpenShift cluster from version 4.16.38 to 4.17.25. The cluster consists of 4 nodes, with 1 node on x86 architecture and 3 nodes on s390x.

After the upgrade, the x86 node was automatically tainted, which was not expected. This taint caused certain workloads to be unschedulable on the x86 node. No manual tainting or node role changes were done during the upgrade process.

Expected results:

    Should behave normally.
