It is currently assumed that each record has it's own (unique) sequence number. The sequence number is used to create nodes in the sysctl tree under hw.mca and when multiple records have the same sequence number, we can't save the record. We get the following error: can't re-use a leaf (57)! It seems that the class of errors for which this happens are those errors for which we need to get CPU-specific errors from each CPU. As the error seems to happen when we get the MCA record from the AP after we got the error from the BSP. >How-To-Repeat: >Fix: >Release-Note: >Audit-Trail: >Unformatted:
