When the module hed is built-in, the init order is determined by Makefile order. That order violates expectations. Because the module hed init is behind evged. RAS records can't be handled in the special time window that evged has initialized while hed not. If the number of such RAS records is more than the APEI HEST error source number, the HEST resources could be occupied all, and then could affect subsequent RAS error reporting.
