In case of recursive EEH errors, the kernel is usually crashed before dumping PHB diag-data for the second EEH error. It's hard to locate the root cause of the second EEH error without PHB diag-data. The patch adds one more EEH option "eeh=early_log", which helps dumping PHB diag-data immediately once frozen PE is detected, in order to get the PHB diag-data for the second EEH error.
