    The above is during a live update. The crash for
    checkpoint/restart will have the same stack for setnewrq and
    setrq. Alternatively, we could hit a breakpoint in
    RQ_THREAD_VALIDATE.

Problem conclusion

  • Set thread's runqueue and homenode before calling setnewrq in
    restart code.
