      This is happening on both GM ptp test environments (helix59 and helix60) 
      Both of these environments were working with the same configs on 4.16 yesterday.
      This is not happening in our OC/BC environment.

      Version-Release number of selected component (if applicable):

      OCP 4.18.0-ec.2
      ptp-operator.v4.18.0-202410222209

      How reproducible:

      100% two environments

      Steps to Reproduce:

          1. Deploy 4.18 SNO with ptp-operator.v4.18.0-202410222209
          2. Check linuxptp-daemon pod - numerous restarts shown
          3. Check linuxptp-daemon-container for error, "panic: interface conversion: interface {} is int64, not int"     

      Actual results:

      pod continuously restarts and operator is not functional    

      Expected results:

      pod starts correctly and operator functions normally
