In the proactive error handling mode, the PMD will set the data path
pointers to dummy functions and then try recovery, in this period the
application may still invoking data path API. This will introduce a
race-condition with data path which may lead to crash [1].

In the proactive error handling mode, the PMD will set the data path pointers to
dummy functions and then try recovery, in this period the application may still
invoking data path API. This will introduce a race-condition with data path
