A couple of issues here: 1) MCE_LOG_LEN is only 32 - so we may have more pending records than will fit in the buffer on high core count CPUs. 2) During a panic we may have a lot of duplicate records because multiple logical CPUs may have seen and logged the same error because some banks are shared. Switch to using the genpool to look for the pending records. Squeeze out duplicated records.
